When you access a website through an Ultraviolet proxy, the service worker intercepts all HTTP requests made by the browser. It then rewrites these requests, concealing their true destination before forwarding them through a safe path to the target server. This process effectively bypasses network-level filters and firewalls that rely on domain names or URL patterns to block content.
While Ultraviolet is an incredibly powerful tool, users must remain aware of its limitations and potential security risks.
It supports WebSockets, CAPTCHAs, OAuth logins, and complex video streaming protocols.
The operator of the Ultraviolet instance can technically view all unencrypted traffic passing through the server. Never log into highly sensitive accounts (like personal banking) using a public instance hosted by a stranger. Always prefer self-hosted options.
