Okena vs Séance

Okena is a native terminal multiplexer for running multiple command-line agents and projects in one window. Workspaces can be arranged as side-by-side project columns, tabs, split panes, detachable terminal windows, or fullscreen. The terminal uses GPU-accelerated rendering and supports scrollback of up to 100,000 lines. Okena can save and restore workspace layouts and terminal sessions across restarts; persistence is local. Users can manage Git worktrees as projects and view branches and change statistics. Documented integrations include status or usage information for Claude Code and OpenAI Codex, Docker Compose project services, and opening files in editors. Remote control is documented through a local HTTP and WebSocket API, with a browser client and iOS and Android companion apps. Pairing uses HMAC-SHA256 token authentication and rate-limited pairing codes, and downloaded updates are SHA256 verified. Okena is free and open source under the MIT License, with a listed plan of free. Installation commands are provided for macOS, Linux, and Windows, alongside instructions for building from source.

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.
