How to Host Your Own 3kh0 Like GitHub & Replit Projects — Build Your Own Ad-Free, Unblocked Mirror.

You can host your own 3kh0-like site by forking a public mirror or starter repo, altering its assets and configuration, and deploying it via GitHub Pages (username.github.io) or via Replit. This gives you full control, avoids downtime of the original, and makes your own copy “unblocked” (in many networks) as long as your domain or URL isn’t restricted.

In this article, you’ll find a step-by-step walkthrough for cloning a 3kh0-style project, customizing it (games, assets, ads), deploying on GitHub Pages or Replit, and working around common network or Cloudflare restrictions. You’ll also get template starter repos, tips on build cleaning and resource optimization, and advice on avoiding blocking. Use this to build your own mirror / variant that’s reliable, performant, and maintainable.

Why mirror or replicate a 3kh0-style project?

Before jumping into code, let’s clarify what features make 3kh0 attractive, and why developers want to host similar projects:

Unblocked games repository

3kh0 provides a catalog of browser games that remain playable even in restricted school or workplace networks.

Proxy / wrapper logic

Many 3kh0 deployments include wrappers or proxying so that game assets or external links aren’t blocked directly.

Ecosystem of mirrors

 Because the original is often blocked, many clones and mirrors exist. For example, there is a version “3kh0.github.io-replit” hosted for Replit environments.

Open source starting point

Several repos (mirrors, alternates, proxy wrappers) exist already, which you can fork and adapt.

So as a developer, replicating a 3kh0-style setup gives you:

• Full control over assets, content, and ads
  
• The ability to manage your own version (in case original is down or blocked)
  
• A good showcase of proxying, wrapper logic, and deployment pipelines
  
• A means to host variations (adfree, localized, etc.)
  

Now let’s go step by step.

Before we get hands-on, it’s important to understand the difference between GitHub Pages and Replit deployment, and when each one is the better choice for hosting your 3kh0-like projects.

Overview: GitHub Pages vs Replit Approach

GitHub Pages (username.github.io)	Replit Deployment (Node.js + Server Logic)
Overview: GitHub Pages is a free, static hosting service directly integrated with GitHub. It’s ideal for serving HTML, CSS, and JavaScript files without needing any server-side configuration.	Overview: Replit allows you to host full-stack applications, including Node.js backends. It’s better suited for running proxy endpoints, dynamic routing, or server-side logic that 3kh0-style projects often require.
Pros: It’s easy to use, completely free, and perfect for static game wrappers or frontends. GitHub Pages supports custom domains, HTTPS, and integrates seamlessly with your repository for auto-deployment.	Pros: Replit lets you run backend code, build APIs, and simulate server-side bypass logic. You can create Express-based proxy routes or serve dynamic assets directly, giving you more control over functionality.
Cons: Since it only serves static assets (HTML/CSS/JS), it can’t handle server-side features like proxying or URL rewriting. For that, you’d need to rely on client-side workarounds or serverless integrations.	Cons: Free Replit plans come with limits — your app might “sleep” after inactivity, face bandwidth restrictions, or load slower due to cold starts. Some advanced features may require paid plans.
Use Case: Best for lightweight 3kh0 mirrors, static frontends, and ad-free versions where no backend logic is needed.	Use Case: Ideal for 3kh0 projects that need proxying, dynamic game loading, or API integrations. It’s great for testing and hosting full dynamic environments.
Example: You can fork 3kh0-ALT/3kh0.github.io and deploy it directly under your GitHub username (e.g., yourname.github.io).	Example: The repository 3kh0/3kh0.github.io-replit is specifically designed for Replit, complete with Node.js proxy scripts and Express configuration.

Pro Tip:
Many developers combine both. You can host the static shell (frontend) on GitHub Pages for speed and stability, while using a Replit backend to handle dynamic features or proxy requests. This hybrid setup provides the simplicity of GitHub Pages and the flexibility of Replit — the best of both worlds.

Step 1: Fork an Example Repository

To begin, fork or clone a working 3kh0 mirror or starter. Some viable options:

• 3kh0.github.io-replit: a mirror adapted for Replit, using Express / Node wrapper.
  
• 3kh0-ALT / 3kh0.github.io: an alternate mirror suitable for static deployment.
  
• 3kh0-mirrors: repository listing mirrors and asset sources you may reuse.
  

Here’s how:

• On GitHub, click “Fork” for the repo you choose.
  
• Clone it locally via git clone https://github.com/yourusername/forked-repo.git.
  
• Create a branch like my-version for your custom changes.
  

You now have the full directory: index.html, projects.html, assets/, js/, css/, maybe server.js (if Node version), etc.

Step 2: Audit and Replace Assets & Links

You’ll want to clean up and customize content so your site isn’t just a copy. Here are key tasks:

Replace Game List & Catalog

Open projects.html or its JS-managed catalog. Replace or prune entries you don’t want. For example, remove blocked games or those with broken links.

If the original uses a JSON index (e.g. games.json), you can rebuild it with your own selection.

Update CSS, Logos, Branding

Swap out logos, color schemes, fonts. In css/ folder or the main CSS file, change brand name references and visual identity. Make sure the base favicon (favicon.ico) is updated.

Proxy / Wrapper Links

Many 3kh0 variants wrap external game URLs to bypass blocked hosts. For example, the path may forward requests via your own proxy endpoint (e.g. /proxy?url=…). If using Node or server logic, locate the proxy handler and adjust how it fetches and rewrites headers.

If your deployment is purely static, you may embed an iframe or clientside fetch with CORS proxies.

Clean up unwanted code

Remove unnecessary analytics, tracking, or ad scripts you don’t intend to run. This helps reduce bloat and potential blocking.

Step 3: Prepare for GitHub Pages Deployment

If your project is purely static or your proxy logic is clientside, GitHub Pages is ideal.

Configure repository name

For user site, name the repository [your-username].github.io. GitHub auto-publishes the main or master branch to https://your-username.github.io. If using a project site (subpath), you can name e.g. my-3kh0-clone and publish under https://your-username.github.io/my-3kh0-clone.

Adjust paths and base URLs

If you’re hosting in a subpath (project site), update all relative asset paths, links, and base tags (in <head><base href=”…”>). Broken asset references are a common error.

Commit and push, enable GitHub Pages

Push your branch to GitHub. In repo Settings → Pages, select branch (usually main) and / (root) folder. GitHub will build and publish.

After a few minutes, your site should be live. Check using https://your-username.github.io.

Add custom domain (optional)

If you want a custom domain (e.g. games.yoursite.com), add a CNAME file in root containing that domain, and set DNS CNAME or A records per GitHub docs.

Step 4: Deploy On Replit (Optional / for proxy logic)

If your site requires server logic (proxying, dynamic rewriting), Replit is a good option.

Import your repo into Replit

Go to Replit, choose “Import from GitHub”, and select your forked repo (or upload). Ensure the .replit file or replit.nix is present (some starter repos already include) so that Replit knows how to run the project.

Create server logic (if missing)

If the repo template is a pure static version, add a server.js or index.js:

const express = require(“express”);

const fetch = require(“node-fetch”);

const app = express();

app.use(express.static(“public”));  // your static files dir

app.get(“/proxy”, async (req, res) => {

  const target = req.query.url;

  if (!target) {

    return res.status(400).send(“No url”);

  }

  const resp = await fetch(target);

  const buf = await resp.buffer();

  resp.headers.forEach((v, k) => {

    res.set(k, v);

  });

  res.send(buf);

});

// fallback route

app.get(“*”, (req, res) => {

  res.sendFile(__dirname + “/public/index.html”);

});

const port = process.env.PORT || 3000;

app.listen(port, () => console.log(“Server started at”, port));

Adjust static folder name and proxy rules accordingly.

Adjust build / start scripts

In package.json, ensure you have:

“scripts”: {

  “start”: “node server.js”

}

And make sure dependencies (express, node-fetch) are listed.

Run and test

Click “Run” in Replit. It should show a URL like yourproject.repl.co. All static pages + proxy endpoints should be accessible. For example, test https://yourproject.repl.co/proxy?url=https://somegame.com/path.

Connect with your GitHub Pages (hybrid approach)

One common pattern: host your UI on GitHub Pages (fast and static) and route proxy calls to your Replit backend. You’d embed fetch or AJAX calls from the frontend to your Replit endpoint (e.g. https://yourproject.repl.co/proxy?…). Just ensure CORS is enabled in your server logic to accept calls from your GitHub Pages domain.

Step 5: Enable / Disable Ads, Monetization

Some 3kh0 clones include ad scripts (e.g. via AdSense, Propeller, or custom ad wrappers). If you wish to monetize:

• Insert ad script tags in your HTML pages (e.g. index.html, about.html, etc.)
  
• Ensure ad domains are not blocked in target networks (school may block some ad domains)
  
• Optionally, include a toggle or config flag so you can disable ads on test mode or for privacy versions.
  

However, be careful: many network filters aggressively block ad domains. Sometimes a better monetization strategy is affiliate links or donations rather than ad embed scripts.

Step 6: Tips to Avoid Blocking & Maintain Availability

Use alternate hosting / mirrors

Even if your version gets blocked, others can host mirrors. The 3kh0-mirrors repo maintains a list of available mirrors and asset hosts you may leverage. Use diverse CDNs or serve assets from GitHub, jsDelivr, or other free CDNs so no single point is blocked.

Avoid exposing origin domains directly

If your game assets or external links refer to domains that are blocked, networks may still block them. Proxy them via your domain (so the request flows through your server or forwarding logic). That way network sees your domain, not the external one.

Minimize external dependencies & third-party scripts

Every external script, banner, ad, or third-party host is a potential block point. Keep your core UI minimal; bundle dependencies rather than loading from unknown sources.

Optimize assets: compress, lazy load, remove dead code

Use Webpack/rollup or another bundler to shrink JS/CSS, tree-shake unused modules, compress images (WebP, etc.). The lighter your build, the faster it loads, fewer timeouts or errors in restrictive networks.

Use “ext remover” or build cleanup

Before deploying, strip unnecessary debug scripts, redundant code, or “.map” files. Many mirrors use a build cleaner to reduce noise. For instance, remove *.map, remove .gitignore in public, prune large log files. This lowers footprint and helps in constrained environments.

Sample Starter Repository Structure

Here’s an example of how your forked project might be structured:

/ (root)

  index.html

  projects.html

  about.html

  404.html

  proxy.html or redirect logic

/public (or `static`)

  css/

    style.css

  js/

    catalog.js

    wrapper.js

  assets/

    images/

    icons/

.gitignore

README.md

package.json (if Node version)

server.js (if needed)

.replit or replit.nix (for Replit deployment)

CNAME (if custom domain)

You’ll want relative linking, route fallback, and proxy endpoints in place. If wanting multi-page navigation, ensure linking works both in root and subpath deployments.

Example Walkthrough: Deploying a 1v1.lol Wrapper

To show a concrete case, let’s wrap a game like 1v1.lol:

• In your projects list (e.g. JSON or projects.html), add an entry with title, icon, and URL: https://1v1.lol/.
  
• In your frontend JS, render a link like /play.html?game=1v1.lol.
  
• Create play.html that reads the game query param and builds an iframe pointing to /proxy?url=….
  
• Your proxy logic (server) fetches https://1v1.lol/ content and streams to the client (rewriting links, injecting CORS headers if needed).
  
• Test in browser: https://yourdomain/play.html?game=https://1v1.lol/ should load the game inside an iframe or similar.
  

If the target site disallows embedding (via frame-ancestors or CSP), you may need to fetch HTML, rewrite <head> tags, and inline CSS/JS. That’s more advanced, but many 3kh0 clones do similar rewriting.

Conclusion

By following these steps, you can build your own 3kh0-style mirror: clone a starter repo, adapt assets and linking logic, deploy statically via GitHub Pages (or hybrid with Replit for proxy logic), and optimize for performance and blocking resistance. Use multiple mirrors, proxy endpoints, clean builds, and minimal external dependencies to stay resilient in constrained networks.

As you iterate, you’ll gain deeper understanding of proxying, dynamic rewriting, host bypass techniques, and static deployment strategies. Over time, your custom clone may even become a go-to alternative when the origin is down or blocked.
