Why plain TCP proxies are not enough!

Even if your SOCKS5 proxy supports UDP, most anti-detect browsers (in particular those based on Chromium) are unable to route WebRTC traffic through a proxy. The reason is the technical limitations of the browsers themselves.

Today captcha systems are increasingly adding enhanced checks for the presence of WebRTC; as an example, Discord has adopted "hCaptcha Enterprise," which already includes a check for whether the user has WebRTC enabled.
