100+ Working Ultraviolet Proxy Links & Instances (Updated 2026)

Why Ultraviolet Proxy Links Go Down So Frequently

Every ultraviolet proxy link is essentially a public URL pointing to a Node.js server. Schools, workplaces, and ISPs maintain blocklists that are updated continuously — often by automated systems that scan for known proxy patterns. Once a domain or subdomain is flagged, it gets added to the filter and stops working for users behind that network.

The second reason links die is infrastructure: free hosting platforms (Replit, Glitch, Railway free tier) have uptime limits or get their accounts suspended when administrators flag proxy use as a terms-of-service violation. A working ultraviolet proxy link from last month may be dead today through no fault of your own.

The most reliable solution is either to use a self-hosted instance you control or to rely on a trusted, maintained proxy website like this one — rather than chasing ephemeral third-party links.

What Is an Ultraviolet Proxy Instance?

An ultraviolet proxy instance is any deployed server running the Ultraviolet stack — the Node.js backend (bare or wisp server) plus the static frontend. Each instance has its own unique URL. The ultraviolet proxy instances community collectively maintains hundreds of these URLs, although the attrition rate is high.

Instances differ from mirrors. A mirror copies the frontend HTML but may point to a shared or down bare server. A genuine instance runs its own transport backend. When evaluating an ultraviolet proxy link, verifying that the bare server responds is more important than checking if the frontend loads.

Where to Find Updated Ultraviolet Proxy Lists

The most reliable sources for an up-to-date ultraviolet proxy list are community-maintained spaces where users actively report which links are working:

GitHub Repositories

Several GitHub repositories exist solely to maintain a curated ultraviolet proxy list. These repos are updated via pull requests from community members — when a link dies, someone submits a PR to remove it and add a new one. Search GitHub for "ultraviolet proxy instances" or "ultraviolet proxy list" to find the most recently updated repos. Look at the commit timestamps — a repo last updated three months ago is likely stale.

Reddit Communities

Subreddits focused on school proxy tools and internet freedom regularly post fresh ultraviolet proxy links free. Threads asking "what proxy works in 2026" reliably surface recently verified instances because users only post links that worked for them recently. Sort by new rather than top to find the most current suggestions.

Discord Servers

The Titanium Network Discord and several affiliated community servers maintain dedicated channels for sharing working ultraviolet proxy links. These channels are often the fastest source of new instances because members post immediately when they find or deploy one. The moderation in these servers also weeds out malicious links more quickly than public search results.

Ultraviolet Proxy on Google Sites

Ultraviolet proxy Google Sites deployments are a clever workaround for school networks that block known proxy domains. Google Sites URLs (sites.google.com/view/...) are on Google's own infrastructure — blocking them would also block legitimate Google services, so many school filters allow them through.

These deployments typically embed the Ultraviolet frontend in an iframe or link to a separately hosted bare server. The setup is technically limited — iframes cannot host service workers, so some ultraviolet proxy Google Sites pages are actually redirects or use alternative transport methods rather than standard Ultraviolet service worker architecture.

They are useful as a gateway but have lower compatibility with complex websites compared to a full Ultraviolet instance. JavaScript-heavy sites (Google Docs, Discord web) may not function correctly through a Google Sites wrapper. Use them when nothing else gets through, but expect reduced site compatibility.

How to Read and Verify an Ultraviolet Proxy URL

A genuine ultraviolet proxy url has recognizable patterns that help distinguish it from imitations or malicious lookalikes:

• The service prefix: When you browse through Ultraviolet, your address bar shows a URL containing /service/ followed by encoded characters. If a proxy claims to be Ultraviolet but the URL structure is completely different, it is probably a different proxy tool.
• The bare/wisp endpoint: Visiting https://your-proxy-url/bare/ or https://your-proxy-url/wisp/ should return a JSON response or a WebSocket upgrade handshake. A 404 at those paths means the backend is missing.
• Service worker registration: On a working instance, opening DevTools → Application → Service Workers shows a registered worker. If no worker registers after loading the page, the proxy will silently fail.

Free Ultraviolet Proxy Links — Safety First

Not all sites claiming to offer ultraviolet proxy links free are safe. Some risks to be aware of when using any third-party instance:

Traffic logging: The operator of any proxy instance can log your browsing history at the bare/wisp server level. They see the destination URLs your browser requests, even if the content itself is encrypted at the TLS layer between the target site and the bare server. Use trusted, known operators — or self-host.

Malicious injection: A compromised proxy can inject JavaScript into every page you load, enabling credential theft or ad fraud. Inspect the bare server code if it is hosted on an open GitHub repo. Check the network tab in DevTools for unexpected scripts loading from unfamiliar domains.

Phishing mirrors: Some sites copy the Ultraviolet frontend design to appear legitimate but route traffic through malicious infrastructure. Stick to instances shared in reputable community spaces rather than links found through Google search results for "free proxy sites."

Building Your Own Personal Proxy Link

The most reliable ultraviolet proxy link you will ever have is one you deploy yourself. A personal Railway or Render deployment takes under 10 minutes and gives you a persistent URL that only you know — meaning it will never appear on a blocklist because it was never shared publicly. Combine it with a custom domain for extra longevity.

Follow the setup guide on this blog for step-by-step deployment instructions. Once your instance is running, you have a permanent, safe ultraviolet proxy url that works on any network — school, work, or public WiFi.

Keeping a Personal Proxy List

Bookmark a short list of 3–5 ultraviolet proxy instances from different hosting providers. When one goes down, switch to another while the first recovers or gets replaced. Diversity of providers matters — an instance on Railway will survive a Replit outage and vice versa. Having instances on completely different domain registrars also helps when a specific TLD gets blanket-blocked on a network.
