Séance vs TermStation

Séance is a free, Linux-only terminal multiplexer for tracking AI coding-agent sessions. It follows Claude Code, Codex, Pi, OpenCode, and Antigravity CLI sessions, and shows whether each is working, awaiting permission, or idle. Permission requests and task completions can generate desktop notifications with unread tracking. Its panes scroll horizontally, with workspaces, tabs within columns, a command palette, focus-follows-mouse, and session persistence across restarts. The app uses GTK4, libadwaita, and libghostty, and supports X11 and Wayland. The `seance ctl` command connects to a running instance over a Unix domain socket; commands can return JSON, manage workspaces and panes, send input, and 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 only the latest release receives security fixes.

TermStation is a web-based terminal session manager with an API for organizing sessions across multiple machines. Configurable templates set CLI commands and arguments, then shape the forms used to create sessions. Session and workspace scratch pads, session links, and file generation with macros and includes support day-to-day work. It can launch commands in containers and route HTTP access to web servers in those containers through a reverse tunnel. Multiple users can work with role-based access and share sessions. Configurable code-forge integrations include GitHub by default; the maker also demonstrates installing Claude, Codex, and Cursor in a container. TermStation is open source under the MIT license and free. It is marked pre-alpha and not ready for general distribution. Backend requirements include Ubuntu 22.04+ or Rocky Linux 10+, Node.js 22+, and Docker or Podman. Authentication exists, but the maker says it is not hardened for untrusted networks and advises against public exposure. Session data must be deleted manually until automatic cleanup is implemented.
