Ultraviolet is a sophisticated web proxy used to bypass internet censorship in a browser. It is popular in school and work environments because it doesn't require installing any software—it runs entirely through a web page. 🛠️ How It Works
Unlike basic web proxies that just fetch a page's HTML, Ultraviolet uses Service Workers to intercept every network request the browser makes.
Code Rewriting: It dynamically modifies a website's HTML, CSS, and JavaScript as it loads.
Asset Redirection: It ensures that images, scripts, and links are rerouted through the proxy server rather than the blocked site directly.
Modern Compatibility: This deep integration allows it to support complex sites like Discord, YouTube, and Spotify that break on older proxies. ✅ Key Features
No Installation: Users just visit a URL; no VPN or browser extension is needed.
CAPTCHA Support: It can handle security checks like reCAPTCHA and hCaptcha.
High Performance: It is designed to be faster than traditional proxies, with minimal lag for video streaming.
Customization: It is open-source and can be hosted privately on platforms like Replit or Vercel. ⚠️ Important Considerations
Privacy Limits: It is built for access, not security. It does not encrypt your entire internet connection like a VPN.
Admin Blocking: Because it is often hosted on public platforms, network admins can block specific proxy URLs fairly easily.
Lifecycle: The project has been largely superseded by newer tools like Scramjet, though it is still widely used in "unblocker" communities.

How to make a Ultraviolet proxy, or connect it with your frontend
Ultraviolet is a popular, open-source web proxy designed to bypass internet censorship and firewalls, commonly used in schools or restricted environments. It works by using a Service Worker to intercept and rewrite HTTP requests, allowing users to browse websites within a "sandboxed" session that appears as the proxy's domain rather than the target site's. Core Features
Interception Proxy: It intercepts requests via a Service Worker script.
High Compatibility: It supports complex web apps like Discord, YouTube, and Google.
Stealth: Features include "About:Blank" cloaking to hide browsing history from local administrators.
Developer Friendly: Highly customizable with many templates available on GitHub. Technical Components
Titanium Network: The primary developer group behind the project.
TompHTTP Spec: The specification Ultraviolet follows for its networking logic.
Bare/Wisp Server: The backend component that actually fetches the data and sends it back to the client.
uv.bundle.js: The core JavaScript file that handles the rewriting and client-side logic. Usage & Deployment
Self-Hosting: Users often deploy it to platforms like Railway or Render using templates.
Templates: Popular versions like Chemical or Easyviolet simplify the setup process.
Static Sites: While the proxy requires a backend, "Static" versions exist that connect to external public "Bare" servers.
💡 Note: Because it is frequently used to bypass school filters, many public links are quickly blocked, leading to the creation of "link hubs" that are updated daily. If you'd like, I can: Provide a guide on how to host your own instance. List some currently active public links.

The legality of using an Ultraviolet Proxy depends entirely on jurisdiction and intent.
Most proxies break video streaming and chat apps. Ultraviolet natively supports WebSocket proxying. This allows platforms like Discord (Web version) or Twitch chat to function seamlessly behind the proxy—a feature virtually unheard of in traditional CGI proxies like Glype or PHProxy.
