Free, open-source Agent Development Environment (ADE) that runs multiple CLI coding agents like Claude Code, Codex, and Cursor side-by-side, each in its own isolated git worktree, tracked in one desktop app.
Orca, built by Stably, is a free and open-source (MIT) Agent Development Environment (ADE) — a desktop app for macOS, Windows, and Linux that orchestrates multiple CLI coding agents in parallel. It works with virtually any terminal-based agent, including Claude Code, Codex, Cursor CLI, Grok, GitHub Copilot, OpenCode, Amp, Gemini/Antigravity, Devin, Goose, Cline, and many more, running each in its own isolated git worktree so you can fan one prompt across several agents, compare their results, and merge the winner. Beyond orchestration, Orca packs a full development workspace: Ghostty-class WebGL terminals with infinite splits and persistent scrollback, a VS Code-style editor with autosave and drag-and-drop of files or images into agent prompts, an embedded Chromium browser with a 'Design Mode' that sends any clicked element's HTML, CSS, and a cropped screenshot into the agent, native GitHub and Linear integration for browsing PRs, issues, and boards, AI-diff annotation for line-level review comments, and SSH worktrees to run agents on a remote box with auto-reconnect and port forwarding. A mobile companion app for iOS and Android lets you monitor and steer agents and get notified when they finish. The Orca CLI (orca worktree create, snapshot, click, fill) lets agents themselves script Orca workflows, and Computer Use lets agents operate desktop apps. Account switching tracks Claude and Codex usage and rate-limit resets. Installation is via direct download, Homebrew, or AUR; the team ships new features daily. Best for power users and teams running many AI coding agents at once. No MCP server/client is documented; integration is through the supported CLI agents.
