About
Orca is an agent development environment that runs 20 or more coding agents in parallel, each in its own isolated git worktree, so you can compare results and merge the winner. It works with Claude Code, Codex, OpenCode, Grok, and others, and it runs on your own model subscriptions with no per-seat licensing. If you want to stop babysitting one agent at a time and start running them like a team, this is the setup.
Details
Open source. You run it yourself.
Auth: Open source (MIT)
Rate limit: Self-hosted open source: no platform limits; model usage billed by your own provider.
