A free image hosting solution for AO3 and elsewhere - A Tutorial (mobile-friendly!)

See the demo site made from this template IN ACTION: https://hotlink-archive-template.pages.dev/

This guide is for an easy, mobile-friendly way to host files for hotlinking on AO3 or elsewhere, using github and cloudflare pages.

I've encountered far too many dead links in fanfics and forums simply because a hosting service decided to dump older files, or they decided to change their TOS to no longer allow hotlinking or certain kinds of content (nsfw, fictional graphic content). See Optional Steps for even more options.

This is an easy, barebones way to permanently host images that you don't want deleted unexpectedly or that you can't host elsewhere. (Emphasis on barebones. This will not be a nice portfolio style site. Unless you decide to code that yourself!) You can follow the link above for an example of this type of site.

It is also EASY to upload and use on mobile devices after initial setup!

Tools you will need:

Cloudflare Pages/Workers is a free to use static site hosting service. This will publish your files and make them available online. This will publish your files and make them available online. There is a limit to the amount of data you can upload for free, but you can pay for proper hosting if you want to exceed it.

Github is a code sharing/storage platform. Your files will go here first before being published on Pages. You can edit and upload files through your browser at github.com, or through Github Desktop, a program you install on your computer. There are limits to Github repositories, but they are also generous (suggested 1GB to 5GB per repo).

Basic Setup

1. Create a github account

2. Copy this template repository hotlink-archive-template

Your website will be contained in a repository, a place where all the files and the revision history for your project are stored.

This template repository uses an "Action" (using python) to automatically create a "home" page with an Index of all the files in your repository every time it is updated.

NOTE: I recommend you set your repository to Private. Github's history feature is extensive, so if you have sensitive content or think you might want to delete something later, it will be hard to get rid of it completely once it's been committed and publicly available.

3. Enable Action permissions

In order for the Action script to work, you need to give Actions permission to read and write in your repository.

Within your repository, go to the tab Settings > Actions > General > Workflow Permissions

4. Create a Cloudflare account

5. Create a Pages (or Workers) project and link it to your Github repository

Your Pages project will create the front end of the site where the images will be displayed. You will be able to link those images to other platforms like AO3.

You can create either a Workers or Pages project by going to Add > Pages (or Workers). Name your project WISELY! This name will be your site's URL.

Workers vs. Pages

Workers is subsuming Pages on Cloudflare and now has all the same static hosting capabilities, in addition to its original server-side processing services. If you'd like to, read more about this.

While Workers has similar capabilities, I recommend Pages for this project. Pages has the added bonus of a cleaner URL if you do not have your own domain: “MySite.pages.dev” in Pages vs Workers' “MySite.username.workers.dev”

You will be prompted to import an existing Git repository. You will need to give it access to your Github to do this.

Select the repository on your Github you made for your project, then hit "Begin Setup".

Name your project WISELY! This name will be your site's URL.

You do not need to change any settings on the next page, so hit "Save and Deploy". Your image hosting site will now be live!

The URL will be "https://ProjectName.pages.dev". It may take a few minutes to become accessible.

Now you're done with the basic setup!

How to Add files

You can add any files you want to link to on AO3/elsewhere through mobile, desktop browser, or the Github desktop program!

Here is how to do it on Github.com:

Open up the repository that you made (it can be found at github.com/username/repositoryname). You will see a list of folders and files that are in that repository.

Click into the folder "fan-stuff".

In the top right, go Add file > Upload files and drag in the images you want added. You will need to name the images BEFORE you upload them, as there is not an easy renaming feature within Github's browser interface.

In the Commit changes box, choose a title for what action you are doing. This will help you backtrack uploads if needed.

For example, it could be "Uploaded Batman Art". Make sure it's set to "commit directly to the main branch", then commit those changes. This will upload the files.

Now, if you visit your site, you will see your uploaded image under the "fan-stuff" folder!

To embed/link your image, navigate to your file on your Pages site and copy the URL in the address bar. This URL is what you will use to embed your photo (using HTML or "add image as URL" tools some sites have).

Continue onto More Setup to customize your site and implement more advanced settings. See Tips/Troubleshooting if you're running into problems.

More Setup

Perform site customization/advanced setup with Github Desktop on your PC

Github’s web UI is great, but it has major limitations. I highly recommend that you use Github Desktop during the initial setup, as well as when you want to make major organizational changes to your files/site. Once you have everything set, though, you can use Github in your browser to upload whatever files you want to hotlink at the moment.

Download Github Desktop and “clone” (download a copy of) the repository you made.

This is the best time to rename/rearrange folders + files, etc.

There are other methods in the Troubleshooting section if you need, but Github Desktop is by far the easiest way

see Adding/Renaming Folders for important info on how to properly rename/add folders

see About the Index Page for how to customize your Index pages

Once you’re done editing, “push” (upload) all the changes you made to your online Github repository.

Having some sort of text editor like Notepad++ is useful for editing any code, the automatic color-coding is very helpful. You can edit in plain old Notepad as well, it just won’t look as nice.

About the Index Page

The template repository uses a python Action to automatically create an HTML "home" page with an Index of ALL the files in the folder every time it is updated.

This is particularly convenient for mobile use, as you can upload a file, and the python action automatically updates the Index page.

If you don’t want this, just disable the “create-index” Action and delete the .py files. You can just type in the file locations to get to each file, or you can manually maintain an home/Index page yourself, which isn't hard if you know some basic HTML and can remember to do it consistently.

Also note that if you wish to change any of the content on your Index pages, you must edit the "index.py" file, not the "index.html" file. The "index.html" file gets re-written every time the "create-index" Action is run in order to keep the file index up to date.

Adding/Renaming/Deleting Folders

Disclaimer: This is a bit convoluted because I am extremely unqualified to be working with python OR HTML. There’s probably an easy way to do this, but I don’t have the skill to do it, and most of the stuff here is copied from stuff I found around. If you know a better way to do things, please let me know, it’d make my life easier too!

Adding or renaming folders involves some extra steps.

1. The "index.py" file inside the folder needs to be edited to match the parent folder name.

The place you need to do this is found near the top of the file (highlighted below)

2. Then the outer-most "create-index.py" file needs to be updated to match the new name as well. If you’ve added a new folder, duplicate and adjust the code to match.

The place you need to do this is found at the bottom (highlighted below)

If you don’t need any folders at all, great! Just delete them and their contents! No need to edit any files. (Don’t delete “index.html” or “create-index.py” or “.github/workflows”!)

If you would like to have these folders for later use, leave them as-is and simply edit the index files.

The relevant lines of code at the bottom of "create-index.py" like in the previous step for renaming folders. You may delete this code, or comment it out (using # at the beginning of a line will make it “invisible” to the computer)

Then, add the folder’s name to the “exclusions” list at the top of the "create-index.py" file so that it doesn’t show up on your Index page (highlighted below)

You can also use this same concept to create "invisible" files/folders. Any files/folders included in the "exclusions" list in "(create-)index.py" will not be listed on the Index page, however they can still be found through the direct URL to the file.

On the flipside, this means simply hiding the file/folder from the Index page does not get rid of the file from your site. Anyone who has the URL will be able to find that file unless you remove it, or move its location to change the URL

Tips/Troubleshooting

(Re)name your files before uploading

It’s not possible to rename image/media files on Github’s web UI (it is possible with the local Git program). The "create-index" Action lists out the names of your files exactly, so you will end up with ugly strings of numbers and letters on your Index page if you don't rename them, which is terrible to look at and also plain old CONFUSING to navigate.

So if you're uploading on mobile or through Github on browser, name your files with easy to remember and distinctive filenames before you go ahead and upload them. This makes everything much easier, and it makes your Index page look nice :)

My website isn’t updating when I edit my Github repository!

Check to see if your Pages is retrieving from the correct branch, and if it has automatic deployments enabled.

Can’t see your Github repository when trying to link it on Cloudflare?

Check your Github applications Repository Access settings. Go to your ACCOUNT Settings > Integrations - Applications > Cloudflare > Repository Access

Index action is failing!

Go back to step 3 in Basic Setup and check if you’ve given Actions permission to read and write. If that’s not the issue, check to see if you’ve set up your "index.py" files correctly. The folder names should correspond to the parent folders, and the "create-index.py" file in the outer-most folder should have the correct folder names at the VERY BOTTOM.

How do I rename a folder (or move a file) in Github’s web UI?

It isn’t possible to directly rename a folder in Github’s web UI, doing it using Git on your computer is the most foolproof way to do it. But there is a way (except for media files).

Go into the folder you want to rename and select a file such as “index.html” and enter the “edit” mode.

Go to the file name and backspace until you can edit the parent folder name as well. This will create a new folder with the new name.

You’ll have to do this to every file in the folder until they’re all in the new folder.

Unfortunately, you can’t do this with media files like png/jpg/etc, because entering the “edit” mode on a photo “breaks” it somehow, and bye-bye image :’) (Don’t worry if this happens, just don’t commit the change or roll it back in your history).

Optional Steps

Make deployment (semi-)Manual

You can play with cloudflare and github to make deployment of your site a manual step you have to trigger, instead of automatic with each commit (default setting). This is a safeguard in case you accidentally make a change or delete something from your github, it won't affect your website.

Deploy w/ Branches

You could do a semi-automatic deployment with a "Production" branch on your github that is separate from the branch you edit. This creates an extra step before anything is published on Cloudflare. A safeguard against accidental changes/deletion of sorts :)

Go to Settings > Build tab > Branch Control

Choose your Production Branch (MAIN or CLOUDFLARE) and enable (or disable) automatic deployments

If you choose MAIN, every change you commit to MAIN will be published to Pages

If you choose CLOUDFLARE, any changes you make to MAIN will not show up on your Pages site until you Pull from MAIN to CLOUDFLARE

To Pull changes from MAIN to CLOUDFLARE, go to your github repository

Above your files on the Left, you will see a toggle to choose which branch you are on.

Choose Cloudflare. There will be a message like "This branch is 7 commits ahead of, 2 commits behind main." Click "2 commits behind"

Click "Create a Pull Request". Then click "Merge Pull Request". If everything is correct, this should trigger a build on your Cloudflare

Deploy w/ Github Actions

Or you can create a manual command that you have to enter on github to trigger a deployment on cloudflare. If you're paranoid about anything happening to your site due to a mishap on the Github side, this is a safe choice. Unless you manually trigger the command, your Pages site will be completely untouched no matter if something happens to your repo.

This can be done in many ways, I think the most straightforward is with Deploy Hooks (maybe in conjunction with Actions if you want to make it mobile-friendly), and might be a bit complicated, but not too hard to figure out with some Google-fu.

Here’s some links I think will be useful (note: I don’t use this method, so these haven’t been tested)

Manual trigger action tutorial

How to configure Github webooks

Storing Locally instead of on Github

Although this guide is written with Cloudflare's Github integration in mind, particularly for easy online/mobile access, you can also keep your files locally on your PC and directly upload your assets onto your Pages project. This gives you full control over what happens to your files. (Keeping backups is a good idea. You can still use Github Desktop to do this, just keep your repository on your PC.)

Simply clone/download the repository as it is, customize it as you like, and create a NEW Pages project on Cloudflare, using "Direct Upload" to upload your files

Once you have connected a Pages project with Github, there is no way to change the deployment method to Direct Upload or vice versa. Direct Upload is also not available for Workers.

One thing that will NOT work the same is the "create-index" Action that only works on Github.

I have made a "create-index.exe" that will execute the "create-index.py" files in the exact same way as they would work with the Action. You do not have to install python for this to work (if I did everything right). Simply run "create-index.exe" whenever you make a change and want to update the "index.html" files

Remember, this is EXACTLY THE SAME as the "create-index" Action, meaning you have to edit each "index.py" file when you rename folders, add a folder, want to exclude a file from the Index page, etc. (See Adding/Renaming Folders for how to do this)

Find me on Bluesky. Or if you have a problem, open an Issue on this project :)

I'll try to answer your questions as best I can! But really, I am the most amateur of amateurs and figured this all out using Google, so I might not be of much help ^^;

I also recommend Squidge Images (an offshoot of Squidge.org) as a fairly trustworthy alternative. However, Squidge Images does have some additional rules that Squidge does not, and what crosses the line is at their discretion.

I also posted this over on AO3!

What is Generative Artificial Intelligence-All in AI tools

Generative Artificial Intelligence (AI) is a type of deep learning model that can generate text, images, computer code, and audiovisual content based on prompts.

These models are trained on a large amount of raw data, typically of the same type as the data they are designed to generate. They learn to form responses given any input, which are statistically likely to be related to that input. For example, some generative AI models are trained on large amounts of text to respond to written prompts in seemingly creative and original ways.

In essence, generative AI can respond to requests like human artists or writers, but faster. Whether the content they generate can be considered "new" or "original" is debatable, but in many cases, they can rival, or even surpass, some human creative abilities.

Popular generative AI models include ChatGPT for text generation and DALL-E for image generation. Many organizations also develop their own models.

How Does Generative AI Work?

Generative AI is a type of machine learning that relies on mathematical analysis to find relevant concepts, images, or patterns, and then uses this analysis to generate content related to the given prompts.

Generative AI depends on deep learning models, which use a computational architecture called neural networks. Neural networks consist of multiple nodes that pass data between them, similar to how the human brain transmits data through neurons. Neural networks can perform complex and intricate tasks.

To process large blocks of text and context, modern generative AI models use a special type of neural network called a Transformer. They use a self-attention mechanism to detect how elements in a sequence are related.

Training Data

Generative AI models require a large amount of data to perform well. For example, large language models like ChatGPT are trained on millions of documents. This data is stored in vector databases, where data points are stored as vectors, allowing the model to associate and understand the context of words, images, sounds, or any other type of content.

Once a generative AI model reaches a certain level of fine-tuning, it does not need as much data to generate results. For example, a speech-generating AI model may be trained on thousands of hours of speech recordings but may only need a few seconds of sample recordings to realistically mimic someone's voice.

Advantages and Disadvantages of Generative AI

Generative AI models have many potential advantages, including helping content creators brainstorm ideas, providing better chatbots, enhancing research, improving search results, and providing entertainment.

However, generative AI also has its drawbacks, such as illusions and other inaccuracies, data leaks, unintentional plagiarism or misuse of intellectual property, malicious response manipulation, and biases.

What is a Large Language Model (LLM)?

A Large Language Model (LLM) is a type of generative AI model that handles language and can generate text, including human speech and programming languages. Popular LLMs include ChatGPT, Llama, Bard, Copilot, and Bing Chat.

What is an AI Image Generator?

An AI image generator works similarly to LLMs but focuses on generating images instead of text. DALL-E and Midjourney are examples of popular AI image generators.

Does Cloudflare Support Generative AI Development?

Cloudflare allows developers and businesses to build their own generative AI models and provides tools and platform support for this purpose. Its services, Vectorize and Cloudflare Workers AI, help developers generate and store embeddings on the global network and run generative AI tasks on a global GPU network.

10 Mind-Blowing Ways Cloudflare is Transforming the Tech Industry

It is crucial to ensure your website has strong security and optimal performance in the ever-changing IT world. Here's where Cloudflare becomes a revolutionary solution. Here we will explore Cloudflare, its many uses, how it is revolutionizing the tech industry, and how you can use its features to improve your online visibility.

The Background of Cloudflare-

The goal behind starting Cloudflare was to assist website owners in improving the speed and security of their sites. When it first started, its primary function was to use its content delivery network (CDN) to speed up websites and defend them from cyber threats. To put it simply, Cloudflare is a leading provider of performance and security solutions.

What is Cloudflare?

Cloudflare is the leader in CDN solutions that make connections to your website safe, private, and quick. It is a provider of online architecture and website security services. In its most basic definition, a content delivery network (CDN) is a collection of servers located all over the world. Their primary purpose is to collaborate in order to accelerate the transmission of web content.

In modern times, websites and web applications are widespread. We can find a website or web application to accomplish a variety of tasks. The majority of these websites and web applications are designed to be private and safe, but many small firms and non-techies have restricted access to their security guidelines. These kinds of websites benefit from Cloudflare's performance and security enhancements. Enhancing the security, performance, and dependability of anything linked to the Internet is the goal of Cloudflare, an Internet organization company. The majority of Cloudflare's essential capabilities are available for free, and it has an easy-to-use installation process. Cloudflare offers both UI and API for administering your website.

How Cloudflare is revolutionizing the tech sector-

IT and security teams will have to deal with emerging technology, risks, laws, and growing expenses in 2024. Organizations cannot afford to ignore AI in particular. Those who can't immediately and drastically change will find themselves falling behind their rivals. However, given that 39% of IT and security decision-makers feel that their companies need more control over their digital environments, it is more difficult to innovate swiftly.

How can you regain control and guarantee that your company has the efficiency and agility required to develop while maintaining security? A connection cloud is an all-in-one platform that links all of your domains and gathers resources to help you take back control, cut expenses, and lessen the risks associated with protecting a larger network environment.

Cloudflare is the top and best cloud hosting provider for connection. It enables businesses to lower complexity and costs while enabling workers, apps, and networks to operate quicker and more securely everywhere. With the most feature-rich, unified platform of cloud-native products and developer tools available, Cloudflare's connection cloud gives every organization the power to operate, grow, and expedite its business.

How does Cloudflare work?

Cloudflare improves website speed and security. It offers a content delivery network (CDN), DDoS defence, and firewall services. It safeguards websites against online dangers such as viruses and DDoS assaults. In short, Cloudflare protects websites from internet threats and improves their performance. Additionally, because of its global network, Cloudflare can efficiently handle online traffic and maintain site security.

How to Use Cloudflare?

Website owners must create an account and add their websites to the Cloudflare dashboard in order to use Cloudflare. In addition to automatically configuring its CDN and security capabilities, Cloudflare will check the website for DNS (Data Name Server) records. Website owners can use the dashboard to monitor and modify Cloudflare's settings after they have been set up.

What Makes Cloudflare Useful?

Cloudflare ensures that your website is always accessible, minimises malicious traffic, and speeds it up. Sites maintained using this are more dependable, quick, and safe. Using technologies like SSL (Secure Sockets Layer) and firewalls also simplifies handling DNS (Data Name Server) and security related to websites. It is accessible to all users, regardless of the size of the business. Your website will remain safe, load swiftly, and function flawlessly, thereby ensuring that users are satisfied with uncommon moments of inactivity.

It is a valuable tool for individuals and businesses, is a smart investment for website owners. It enhances the speed, dependability, and security of websites, all at a reasonable cost. This cost-effectiveness ensures that website owners, regardless of their technical proficiency, can feel financially secure and smart.

Benefits of Cloudflare:

The primary benefit is that it offers performance and security at no cost on a bigger scale.

Most of its essential functions are available on a free account.

It functions as a CDN to speed up the speed at which websites load.

It prevents DDoS attacks and harmful bots.

It offered short TTL-managed DNS (Data Name Server).

It offers a free SSL (Secure Sockets Layer) certificate that is updated yearly and is fully maintained.

It offers serverless features and forwarding rules.

Different independent add-ons for different services are available on it.

It offers services for registering domains.

Offers an API to control the majority of the services.

HTTP/2 Protocol: Utilize Parallel Loading to Accelerate Your Website

The outdated HTTP/1.1 standard is replaced by the faster and more modern HTTP/2 protocol. Because it can load page elements concurrently, your website will load more quickly. Because Cloudflare supports HTTP/2, you may benefit from this cutting-edge technology without having to perform any extra effort.

2. Free SSL (Secure Sockets Layer) Certifications

To ensure safe data transfer between your website and users, Cloudflare provides a free SSL certificate. Because search engines give priority to particular websites, this safeguards important information and improves your website ranks.

3. DNS Security: Boost Domain Protection with DNSSEC DNS Security Extensions

DNSSEC confer an additional degree of protection to your domain by authenticating DNS answers. The DNSSEC functionality from Cloudflare is simple to set up and guards against cache poisoning and DNS (Data Name Server) spoofing attacks on your website.

4. Limiting Rates to Prevent DDoS Attacks

A security measure known as rate limitation restricts the quantity of queries visitors can make to your website in a certain amount of time. Because of Cloudflare's rate-limiting feature, your website is shielded from unwanted traffic and DDoS attacks, making the internet a safer place.

5. Image Optimization: Utilizing Compressed Images for Quicker Loading

With Cloudflare's image optimization tool, your website will load faster by resizing and compressing photos. It reduces bandwidth utilization and enhances user experience, which lowers hosting expenses.

6. Page Rules: Edit Specific Pages' Settings

You can adjust caching, security, and other configurations for specific pages on your website using Cloudflare's page rules feature. You may customize the performance and security of your website with this level of control.

7. Browser Caching: Quicken Page Loading

Through browser caching, you can speed up subsequent visits to your website by saving its content on the user's device. The browser caching function from Cloudflare dynamically adjusts cache settings to guarantee peak performance.

8. Network Routing Optimization

Data is transferred effectively across Cloudflare's global network thanks to its improved network routing technology. This leads to enhanced website performance and quicker load times.

9. Minimization: Simplify Your Files to Allow for Quicker Loading

To minimize file size and speed up load times, minimization eliminates superfluous characters from files, like whitespace and comments. By supporting HTML, CSS, and JavaScript files, Cloudflare's minimization functionality makes sure your website functions properly.

10. WebSockets: Allow for Real-Time Interaction

With the help of web sockets, your website's server and browsers may communicate in real time, providing functions like live chat and notifications. WebSockets can be easily implemented on your website using Cloudflare's support for them.

11. AMP Genuine URL: Present Source URLs in Google AMP Search Results

Although they may show a different URL in search results, Google's Accelerated Mobile Pages (AMP) can enhance your site's performance on mobile devices. Maintaining your brand identification and search engine rankings is made easier with Cloudflare's AMP Real URL functionality, which makes sure that your original URL is displayed.

12. Cloud WAF: Protect Your Website from Common Attacks

Web Application Firewalls (WAFs) defend your website against DDoS attacks, cross-site scripting, and SQL injection, among other major online dangers. Strong defence against these attacks is offered by Cloudflare's Cloud WAF, guaranteeing the security of your website.

13. Load Balancing: Allocating Traffic to Ensure Maximum Efficiency

To ensure steady performance, load balancing divides traffic among several servers. Your website will always be quick and responsive, even during spikes in traffic, thanks to Cloudflare's load-balancing technology, which helps avoid server overload.

Conclusion-

You can protect yourself from online threats and gain technologies like Content Delivery Network (CDN) and (Secure Sockets Layer) SSL/TLS encryption with Cloudflare. It keeps your website safe and quick, and it's simple to use. But if you want to get the most out of your website, don't wait to start using Cloudflare right now. You can be sure that your website is secure and operating efficiently using Cloudflare.

With a free plan for essential functions, Cloudflare provides reasonable price options. For small businesses who require website security and Search Engine Optimization (SEO) but want to save money, this makes it the perfect option. Plus, compared to other CDN providers on the market, its premium plans are fairly priced.

Tip: Cloudflare Workers don't save logs, so you can only access them in real time... unless you make a Discord webhook out of a muted channel in your personal server and send them over there!

Edit: Oh, and I had to switch to "types": ["@cloudflare/workers-types/experimental"] in tsconfig.json to get this to typecheck. A regular fetch seemed to work fine too, but navigator.sendBeacon seemed more semantic.

Quote of the Week

In [other languages], I could end up chasing silly bugs and waste time debugging and tracing to find that I made a typo or ran into a language quirk that gave me an unexpected nil pointer. That situation is almost non-existent in Rust, it's just me and the problem. Rust is honest and upfront about its quirks and will yell at you about it before you have a hard to find bug in production.

Edge Computing for Web Developers: How to Speed Up Your Apps

In today’s digital race, milliseconds matter.

Whether you’re building a real-time dashboard, an e-commerce platform, or a SaaS product, users expect one thing — speed. But traditional cloud setups, while powerful, aren’t always fast enough when data has to travel halfway across the globe.

Enter: Edge Computing — a game-changing strategy that moves computing closer to users and supercharges web performance.

What Is Edge Computing (And Why Should You Care)?

Imagine you’re ordering pizza. Would you rather get it from a kitchen next door or one 500 miles away?

That’s the difference between centralized cloud and edge computing.

Edge computing is about processing data as close to the user as possible — often on local servers or network nodes instead of a distant data center. For web developers, this means fewer delays, faster responses, and smoother user experiences.

And in an age where a one-second delay can drop conversions by 7%, that’s a big deal.

How Does It Actually Work?

Here’s the simple version:

You deploy some parts of your app (like APIs, static files, and authentication logic) to a central server and across multiple edge locations worldwide.

When a user in New York accesses your app, it loads from a nearby edge server, not from a main server in Singapore.

Result? Lower latency, less server load, and faster load times.

What Can Web Developers Use Edge Computing For?

Edge computing isn’t just for heavy tech infrastructure — it’s now developer-friendly and API-driven. Here’s how you can use it:

1. Deliver Static Assets Faster

CDNs (Content Delivery Networks) like Cloudflare, Vercel, or Netlify already do this — they serve your HTML, CSS, JS, and images from edge locations.

Bonus Tip: Combine with image optimization at the edge to slash load times.

2. Run Serverless Functions at the Edge

Think dynamic actions like form submissions, authentication, or geolocation-based content. Platforms like Cloudflare Workers, Vercel Edge Functions, and AWS Lambda@Edge let you run logic closer to your users.

Example: Show region-specific content without needing the user to wait for a central server to decide.

3. Improve API Response Times

You can cache API responses or compute lightweight operations at the edge to reduce back-and-forth trips to the origin server.

Imagine: A travel app loading nearby attractions instantly by computing distance at the edge, not centrally.

4. Secure Your App Better

Edge networks can block threats before they ever reach your main server, including bots, DDoS attacks, and suspicious traffic.

It’s like having a security guard posted on every street corner, not just your front door.

But… Does Every App Need Edge Computing?

Not necessarily. If your app is local, low-traffic, or non-latency-sensitive, traditional cloud might be enough.

But if you’re scaling globally, working with real-time data, or want lightning-fast load speeds, edge computing is your secret weapon.

Real-World Impact: Numbers Don’t Lie

Vercel reported a 50% performance boost for apps deployed with edge functions.

Retailers using edge caching see a 20–30% decrease in bounce rates.

Streaming platforms improved video start times by up to 60% with edge delivery.

These aren’t just nice-to-haves — they’re competitive advantages.

Getting Started: Tools You Should Know

Here are a few platforms and tools that make edge computing accessible for developers:

Cloudflare Workers — Write JavaScript functions that run at the edge.

Vercel — Perfect for Next.js and frontend teams, with edge function support.

Netlify Edge Functions — Simplified edge logic built into your CI/CD.

AWS Lambda@Edge — Enterprise-grade, with tight AWS integration.

Pro tip: If you’re already using frameworks like Next.js, Nuxt, or SvelteKit, edge-ready deployments are often just one setting away.

Final Thoughts: Why This Matters to You

For developers: Edge computing lets you build faster, more responsive apps without reinventing your stack.

For business owners: It means happier users, lower customer loss, and more conversions.

In a world where speed = success, edge computing isn’t the future — it’s the edge you need today.
