OpenFlux

What it is

A Go tunnel that moves IPv4 TCP and UDP traffic between a client and an exit node through swappable transports, including shared-document services like Yandex.Docs and Mail.ru Docs, a direct link, or transports written in a signed JavaScript engine. Exit nodes forward traffic either as raw L3 with SNAT/DNAT on Linux or through a userspace gVisor L4 proxy on any OS. Clients offer either a SOCKS5 proxy or a full TUN tunnel, and support sessions spread across several transports, failover, AES-256-GCM encryption when enabled, plus an SSH wizard that sets up exit nodes. People researching network stacks and unusual transport channels run both ends themselves.
