Surge snell implemented in Go.
- All complete features except the v5 QUIC proxy.
- Behavior as consistent with the official implementation as possible.
- Performance at least on par with the official implementation.
Surge believes that being closed-source and not proliferated can keep this protocol covert, but this is already impossible in 2026. Considering that snell still has advantages that other random-traffic protocols do not possess, such as multiplexing support with complete TCP semantics and traffic-characteristic diversity, we made this instead of reinventing the wheel.
