tmate

tmate enables real-time collaboration with a single command, generating secure SSH connection strings for instant access, as highlighted in its instant sharing feature.

As a fork of tmux, it maintains full compatibility with tmux workflows and commands, making adoption seamless for existing tmux users.

It uses SSH for all connections, ensuring encrypted and secure terminal sharing, which is a core part of its value proposition for sensitive tasks.

Shared sessions remain active even after the host disconnects, allowing continuous collaboration without interruption, as noted in its session persistence feature.
