Orca is an AI orchestration platform enabling developers to run multiple AI coding agents (e.g., Codex, ClaudeCode, OpenCode, Pi) in isolated git worktrees, tracked centrally. It supports real-time monitoring and remote control via a mobile app (iOS/Android), allowing users to receive notifications and send follow-up prompts. The system features Ghostty-class terminals with WebGL rendering, infinite splits, and persistent scrollback. It integrates with Chromium-based UIs to extract HTML/CSS for agent prompts and allows in-app PR/issue browsing with worktree creation. Remote agent execution includes auto-reconnect and port forwarding. Agents can review diffs, edit files, and commit changes without leaving Orca. Additional features include account switching, usage tracking, and a "Computer Use" mode for desktop app interaction. Orca supports CLI-based agents like Copilot, Grok, and Cursor, with desktop apps available via package managers (Homebrew, AUR) or direct downloads. It is MIT-licensed, with telemetry opt-out options and daily feature updates. The mobile relay component is open-source under the cloud/ directory.
