Séance
What it is
Séance is a free Linux terminal multiplexer that tracks AI coding agent sessions and presents their status in a scrolling pane layout. It automatically follows Claude Code, Codex, Pi, OpenCode, and Antigravity CLI sessions, indicating whether each is working, waiting for permission, or idle. Permission requests and completed tasks can generate desktop notifications, with unread tracking. The interface includes workspaces, tabs within columns, a command palette, focus-follows-mouse, and session persistence across restarts. It uses GTK4, libadwaita, and libghostty, supports X11 and Wayland, and includes blur and transparency. The `seance ctl` command connects to a running instance over a Unix domain socket; commands support JSON output and can manage workspaces and panes, send input, or read terminal output. The project states that it has no telemetry and is licensed under MIT. Installation options include Arch Linux AUR, a Nix flake, and an x86_64 AppImage. OpenCode remote attach sessions and `--pure` launches are not tracked. Séance is pre-1.0, and security fixes are supported only for the latest release.
For and against
For
- Tracks five listed AI coding agent integrations
- Shows working, permission-waiting, and idle status
- Session state persists across restarts
- No telemetry, according to the project
Against
- Linux only, with X11 or Wayland support
- OpenCode remote attach sessions and `--pure` launches are not tracked
- Security fixes cover only the latest release
The verdict
Séance combines terminal panes with status tracking and notifications for supported agent sessions. Check its Linux scope and the stated limits on OpenCode tracking and security support.
Who it suits
Séance suits Linux users who want to monitor supported AI coding agent sessions alongside terminal work. Its command interface may also suit users who want to manage panes and workspaces programmatically.
