Hysteria 2

Hysteria 2 is an open-source proxy and networking platform designed to help users create fast, censorship-resistant, and high-performance proxy infrastructures across unreliable or restricted networks. They provide a QUIC-based proxy protocol that disguises traffic as standard HTTP/3 communication, making it more difficult for censorship systems to detect or block proxy traffic without causing broader network disruption. The platform supports multiple networking modes including SOCKS5, HTTP Proxy, TCP/UDP forwarding, Linux TProxy, and TUN-based routing, allowing users to build flexible proxy and tunneling environments for different networking needs. Hysteria 2 focuses heavily on speed, low-latency communication, and network resilience, especially in lossy or unstable internet conditions.

They also provide advanced capabilities such as custom authentication systems, traffic statistics, access control, and cross-platform deployment support for major operating systems and architectures. Their infrastructure is designed for developers, infrastructure teams, and advanced users who require high-speed encrypted proxy communication, anti-censorship networking, and customizable proxy deployment workflows. Hysteria 2 maintains extensive documentation, developer-friendly specifications, and integration support that simplify adoption across self-hosted networking environments and third-party applications. The project is maintained as an open-source MIT-licensed initiative with an active developer community and ongoing feature development.

And the best part? They offer the platform as a free and open-source censorship-resistant proxy solution, allowing users to deploy advanced QUIC-based proxy infrastructures without licensing costs.
