The protocol is designed to blend with regular HTTPS traffic using TLS encryption and HTTP/2/HTTP/3 transport, making it harder to detect and block than traditional VPN protocols like OpenVPN and WireGuard. TrustTunnel is optimized for mobile platforms and unstable networks. The release includes a protocol specification, reference implementation of server and clients under a permissive license, and client apps for Linux, Windows, macOS, iOS, and Android. Users can self-host their own TrustTunnel servers and configure flexible routing rules. ## Full article daily.dev links to this article rather than hosting it.
