Hysteria is a powerful, lightning-fast, and censorship-resistant proxy.

Wide range of modes including SOCKS5, HTTP Proxy, TCP/UDP Forwarding, Linux TProxy, TUN - with more features being added constantly.

Powered by a customized QUIC protocol, Hysteria is designed to deliver unparalleled performance over unreliable and lossy networks.

The protocol masquerades as standard HTTP/3 traffic, making it very difficult for censors to detect and block without widespread collateral damage.

We have builds for every major platform and architecture. Deploy anywhere & use everywhere. Not to mention the long list of 3rd party apps.

With built-in support for custom authentication, traffic statistics & access control, Hysteria is easy to integrate into your infrastructure.

We have well-documented specifications and code for developers to contribute and/or build their own apps. And a helpful community, too.

If you find Hysteria useful, consider giving it a ⭐️!
