OpenFlux

OpenFlux is a Go project that tunnels TCP traffic through pluggable transports. The client side runs a SOCKS5 proxy, packets travel over a chosen transport, and an exit node on a Linux VPS decapsulates them and forwards them on. Three transports exist today. One carries data inside Yandex Docs cursor messages. Another uses WebRTC data channels through the MAX messenger and is marked experimental, with warnings about account restrictions. The third rides live-coding interview rooms on Cups.online, where the README advises an encryption key because rooms are reachable by anyone who knows their UUID. The exit node runs a userspace TCP/IP stack from gVisor in a default proxy mode that needs no root or raw sockets, plus a raw mode for Linux, and there are an Android client and an iOS client distributed through TestFlight. The author calls it a network stack research tool, states that it is entirely non-commercial, and explicitly does not encourage using it to bypass restrictions or break platform rules.
