One of the major advantages of Ultraviolet is its accessibility. Because it is browser-based, using it is often as simple as finding a working public instance. Users can search for "Ultraviolet proxy links," paste a blocked URL into the provided bar on the proxy's homepage, and begin browsing. and begin browsing.

This process effectively bypasses network-level filters and firewalls that rely on domain names or URL patterns to block content.
You can launch the proxy application locally or on your server by running: npm start Use code with caution.
