| Spec score · Terminal Multiplexers | 7.0 (#26) | 8.0 (#9) |
| Automation | The README says Claude Code agent teams can spawn teammate agents in separate tmux panes inside a psmux session without extra configuration. | The seance ctl command communicates with the running app over a Unix domain socket; commands support JSON output and can manage workspaces and panes, send input, and read terminal output. |
| Installation | The README lists WinGet, Cargo, Scoop, Chocolatey, GitHub release downloads, and building from source as installation options. | The maker lists Arch Linux AUR, Nix flake, and x86_64 AppImage installation options. |
| Requirements | The stated requirements are Windows 10 or Windows 11, with PowerShell 7 or cmd.exe. | Building from source requires Zig 0.16.x, GTK4, libadwaita, OpenGL 4.3+ and Linux. |
| Support | The FAQ directs users to the project's guides for troubleshooting and feature details. | The maker welcomes bug reports, feature requests, and pull requests, and directs questions and show-and-tell to GitHub Discussions. |

In their own words
Séance
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.
