Orca

Orca is an open-source Agent Development Environment (ADE) built by Stably AI for developers who want to run multiple AI coding agents in parallel. It lets users fan a single prompt across many agents — such as Claude Code, Codex, Grok, Cursor, and 25+ others — each running in its own isolated Git worktree, all tracked from one desktop interface. Users bring their own agent subscriptions; Orca itself is free and MIT-licensed, available on macOS, Windows, Linux, and via a companion mobile app for iOS and Android. Key features include a built-in Chromium browser with Design Mode, inline diff review and commit tooling, SSH remote agent support, a CLI for scripting Orca workflows, and real-time mobile notifications when agents finish tasks.
