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.
