Lazy Tmux – Lazy-loading tmux sessions with a tree view
Ever open tmux and dread that your dozens of sessions are all eating memory… or worse, might disappear if a plugin fails?
I used tmux-resurrect + tmux-continuum for years. They “work,” but:
- Sessions sometimes vanish entirely
- With many sessions, everything stays loaded in RAM
So I built Lazy Tmux: https://lazy-tmux.xyz
It shows all sessions as a tree — like they already exist — but only actually loads them when you enter.
- Keep dozens of sessions without bloating memory
- Navigate large session hierarchies quickly
- Lazy-load panes, commands, shells and scrollback history
It’s early, and there are many open issues on GitHub. Feedback, ideas, or contributions are welcome: https://github.com/alchemmist/lazy-tmux
If you’ve ever wrestled with tmux session management, this might make your workflow a lot smoother. Not sure why this got no discussion. I think this such a great tool and has changed how I use tmux! Thank you so much!
