GNU Screen vs Okena

GNU Screen has no write-up on Specifiction yet; its figures are above.

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.
