Colitu Adaptive Connect
How Colitu Adaptive Connect picks a server, tries five connection modes in order, checks that real traffic flows and falls back on its own when one is blocked.
UDP · QUIC · TLS 1.3Hysteria2
Hysteria2 runs over QUIC with TLS 1.3 and its own congestion control. How it works, why it is fast on lossy links, where UDP limits it and how Colitu uses it.
TCP · TLS 1.3 · Reality · XTLS VisionVLESS Reality
VLESS Reality hides a VPN connection inside the TLS 1.3 handshake of a real website, so probes see that site. How it works, its limits and how Colitu uses it.
TCP · XHTTP · Reality · TLS 1.3VLESS XHTTP
VLESS XHTTP carries VPN traffic as HTTP requests over Reality, for networks that cut long TCP connections. How it works, its limits and its role in Colitu.
TCP · TLS 1.3Trojan
Trojan hides VPN traffic inside a standard TLS 1.3 connection with a real certificate, so it looks like HTTPS. How it works, its limits and its role in Colitu.
TCP · AEAD · 2022-blake3-aes-256-gcmShadowsocks 2022
Shadowsocks 2022 (SIP022) encrypts every byte with 2022-blake3-aes-256-gcm and rejects replays. How it works, where it fits and why Colitu tries it last.
What these pages leave out
Server addresses, ports, SNI values and keys are never published; the apps receive connection details encrypted. Here we only explain how the protocols work and how Colitu uses them.
