opensessions is a sidebar for tmux when your sessions, agents, and localhost tabs start multiplying.

It lives inside your existing tmux workflow instead of replacing it: one small pane for session switching, agent state, repo breadcrumbs, and quick jumps back into the right terminal.

Built with Rust and ratatui for native performance and zero runtime dependencies.

Install With TPM

Requirements:

- tmux
- TPM
- curl or wget for downloading prebuilt binaries on first load

Add this to ~/.tmux.conf:

Then reload tmux and install plugins:

Open the sidebar with prefix o → s.

TPM clones the repo into ~/.tmux/plugins/opensessions. On first load, opensessions downloads the matching prebuilt release bundle into bin/; that bundle includes opensessions-sidebar, opensessions-server, and lazydiff.

If your platform is unsupported or you are developing locally, you can still build from source:

If you want the same setup as a single shell command:

Update

Use TPM's built-in update (prefix + U) or run:

No rebuild step:

No local rebuild is needed for normal installs. Reload tmux after TPM updates the plugin; opensessions will download the matching release bundle if bin/…
