How we rank

Evidence notes
  • Evidence level: Verified, primary.
  • Stars are the measure. They look high for its size, so read them as interest, not users.
  • Up from about 42,200 on Aug 11 (Wayback Machine snapshot). Devtoolwatch records 5,000 to 9,600 new stars a week; the repo has about 650 contributors. A 21-point Show HN and one user's UI-bug report suggest the count runs ahead of daily use.

Key facts

As of Nov 11, 2026

Who it's for
Developers supervising parallel agent work and reviewing changes in one workspace.
What is it built on?
An open-source desktop app, with iOS and Android companions. Each agent gets its own worktree, in a chat view or as the raw CLI, with diffs, terminals, a built-in browser and a CLI.
Where do the agents run?
On your laptop, on any SSH host, on a remote Orca server, or in a cloud VM per worktree. Orca does not sell hosting.
Can you run several agents at once?
Yes. One agent can split a task and start worker agents in their own worktrees. You can also send one prompt to several agents and compare the results.
Which models and agents can it use?
Any CLI agent. The README names Claude Code, Codex, Grok, Cursor, GitHub Copilot, OpenCode, Amp, Antigravity, Devin, Kiro and many more.
What do the plans cost?
Free and open source under the MIT license, for macOS, Windows and Linux.
How does billing work?
No charge from Orca. You use your own agent subscriptions.
How many people use it?
122,312 GitHub stars on Nov 11, 2026, up from about 42,000 on Aug 11. Devtoolwatch records 5,000 to 9,600 new stars a week through the autumn. The repo has about 650 contributors and 8,000 open issues.
