opensessions
tmux is all you need. make tmux great again :)
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.
tmux is the only supported mux today. There is older zellij integration code in the repo, but it is not stable enough to document as supported; we are looking for maintainers who want to help bring it back to that bar.
The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
TPM clones the repo into ~/.tmux/plugins/opensessions. It does not install a standalone opensessions binary. opensessions runs from that checkout with your local bun installation.
If you want the same setup as a single shell command:
The plugin automatically restarts the server on update so it picks up the new code. Toggle the sidebar back on with prefix o → s if it was open.
Uninstall
Run the uninstall script before removing the plugin files — it cleans up tmux hooks, keybindings, sidebar panes, and environment variables that would otherwise persist and cause glitching:
sh ~/.tmux/plugins/opensessions/integrations/tmux-plugin/scripts/uninstall.sh
Then remove the set -g @plugin 'Ataraxy-Labs/opensessions' line from ~/.tmux.conf and run prefix + alt + u (TPM uninstall).
Support Status
@opensessions/mux-tmux and the tmux plugin flow are supported.
@opensessions/mux-zellij is still experimental.
The repo is organized for contributors around runnable apps, reusable packages, and host integrations.
Today
Live agent state across sessions for Amp, Claude Code, Codex, and OpenCode.
Per-thread unseen markers for done, error, and interrupted states.
Session context in the UI: branch in the list, working directory in the detail panel, thread names, and detected localhost ports.
Programmatic metadata API: agents and scripts push status, progress, and logs to the sidebar via HTTP.
Fast switching with j/k, arrows, Tab, 1-9, session reordering, hide/restore, creation, and kill actions.
prefix o → s and prefix o → t for sidebar focus and toggle, prefix o → e for sidebar-safe even-horizontal layout in the current window, prefix o → 1 through 9 for quick switching, optional no-prefix shortcuts, in-app theme switching, and plugin hooks for more mux providers or watchers.
Bun workspace, source-first execution, and a local server on 127.0.0.1:7391.
Programmatic API
Scripts and agents can push custom metadata to the sidebar over HTTP — no binary needed:
# Set a status pill on a session
curl -X POST http://127.0.0.1:7391/set-status \
-H 'content-type: application/json' \
-d '{"session":"my-app","text":"Deploying","tone":"warn"}'
# Set progress
curl -X POST http://127.0.0.1:7391/set-progress \
-H 'content-type: application/json' \
-d '{"session":"my-app","current":3,"total":10,"label":"services"}'
# Push a log entry
curl -X POST http://127.0.0.1:7391/log \
-H 'content-type: application/json' \
-d '{"session":"my-app","message":"Tests passed","source":"ci","tone":"success"}'
A Claude Code plugin that automatically captures everything Claude does during your coding sessions, compresses it with AI (using Claude's agent-sdk), and injects relevant context back into future sessions.
