Séance vs Shpool

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.

Shpool is free, open-source software for keeping named shell sessions alive when connections drop. It targets users who want persistence without terminal multiplexing features such as split windows or tiled panes, preserving native terminal scrollback and copy-paste. For SSH, Shpool runs on the remote host and needs no additional client software. Users reconnect with `shpool attach`; the terminal state is redrawn after reattachment. The command line can list, detach, or kill sessions, and `--ttl` sets a session lifetime. Variables in session names and attach options can redirect terminals to newly named sessions when values change. Bash, zsh, and fish support automatic session-name prompt prefixes. The README documents SSH configuration, shell-function patterns, Cargo installation through crates.io, and Homebrew installation on macOS. Shpool supports Linux, macOS, SSH, and command-line shells. It is licensed Apache-2.0, reports zero advisories, and allows only one client per session.
