Orca is an open-source (MIT) desktop app from stablyai for running a fleet of coding agents, including Claude Code, Codex and OpenCode, each in its own git worktree using the user's own subscriptions. Features include fanning one prompt across five agents and merging the winner, commenting on diffs and sending them back, SSH worktrees on remote machines, and a phone app for steering agents. The post reports 103k stars.

TL;DR Orca is an open-source desktop app that runs Claude Code, Codex and OpenCode side by side in separate git worktrees.
Document

What it claims

Orca is an MIT-licensed desktop app from stablyai that runs several coding agents side by side. It supports Claude Code, Codex and OpenCode, and gives each agent its own git worktree. Agents run on the user's own subscriptions, so Orca does not resell model access. The post is by @zyonbuilds and credits @orca_build as the maker. It cites 103k GitHub stars and a date of 23 Oct; the year is not given.

How it works

The post lists four features and no implementation detail:

  1. One prompt can be sent to five agents at once, and the best result is merged.
  2. The user comments on an agent's diff and sends it back to that agent for revision.
  3. Worktrees can live on a remote machine over SSH.
  4. A phone app lets the user check on agents and steer them.

How to use it

Install with the Homebrew cask from the stablyai tap:

brew install --cask stablyai/orca/orca

The source is at github.com/stablyai/orca. Each agent CLI needs its own working subscription.

Limits

The source is a short third-party post on X. It has no benchmarks or merge-quality results, and it does not compare Orca to running agents by hand. Several details are missing:

  • Platforms: Only a Homebrew cask is shown, and the supported operating systems are not stated.
  • Merging: The post does not say whether the "winner" is picked by the user or automatically.
  • Phone app: Its platforms and pricing are not given.
  • Remote machines: The setup needed for SSH worktrees is not described.

The star count and licence come from the post. Check both against the repository before adopting.
