Why tmtv?

I loved tmate but it was stuck on tmux 2.4 from 2017. Nine years of tmux improvements — popup menus, extended keys, sixel graphics — all missing.

So I rebased it on tmux 3.6a, added web sharing, and here we are. Same SSH-based sharing you know, now with a modern tmux and a browser viewer for anyone who just wants to watch. And there's more coming.

Recent updates

1.2.2 2026-03-09 The status bar that keeps its promises. Live viewer counts now work in SSH viewer sessions — see S:2 W:1 update in real time. Fully customizable via status-right, tmux-style.
1.2.1 2026-03-09 Your links now have faces. Session names appear in browser tabs and link previews (Slack, Discord, iMessage). Plus live viewer counts in the status bar — know who’s watching.
1.2.0 2026-03-09 Binaries that actually work everywhere. Fully static Linux builds — no more missing libmsgpackc on Arch or friends. Plus WCAG 2.1 AA landing page for the accessibility-minded sysadmin.
1.1.1 2026-03-09 Your fish finally have the right colors. Fixed 256-color, RGB, and bright palette rendering in the web viewer.
1.1.0 2026-03-08 Named sessions so you can stop sharing random hex. Web sharing toggle — because sometimes you want an audience, sometimes you don't. Plus SSH read-only viewer.
