Orca
Desktop environment for running Codex, Claude Code, OpenCode and Pi in parallel git worktrees, with a mobile companion
Install
brew install --cask stablyai/orca/orcamacOS. For Arch Linux: yay -S stably-orca-bin.
This is third-party code. Review the repository files before installing.
What it does
Orca runs several coding agents side by side, each in its own git worktree, and shows their work in one window. You can send one prompt to five agents, compare results and merge the best. Agents run on your own subscriptions. Orca also ships skills for the agents: orca-cli controls worktrees, terminals and the embedded browser, orchestration coordinates workers with tasks and waits, and there are skills for Linear and emulators. An iOS and Android companion app notifies you when an agent finishes and lets you send follow-ups from your phone.
Who it is for. For developers juggling several tasks with different agents who are tired of terminal tabs.
Good fit when
- You want to run one task across several agents and pick the best result
- Several branches run in parallel and changes must not mix
- You want to monitor agents from your phone
Not a fit when
- One agent in one terminal is enough
- You cannot install desktop apps
Example request
Hand this task to Codex and Claude Code in separate worktrees and tell me when both finishLimitations
Agents and their subscriptions are installed separately. On Linux outside Orca terminals the orca command points to the GNOME screen reader, so the CLI is invoked as orca-ide there.
How to disable. Uninstall the app, for example brew uninstall --cask orca on macOS, and remove Orca skills from the agents' skills directories.
Security check
- Runs several agents that execute commands and change code in parallel
- Enables remote control of agents from a phone
README in short
The README lists features: a mobile companion, parallel worktrees, running different agents side by side and tracking them in one place. Install via builds for macOS, Windows and Linux, a Homebrew cask or AUR; iOS via App Store and TestFlight, Android via APK. A guide covers orca serve on headless servers. MIT licensed.
FAQ
Is a separate Orca subscription required?
The README says agents run on your own subscriptions.
Can it run headless?
Yes, orca serve covers headless Linux servers and has its own guide.
