Orca

Orca is an open-source, cross-platform Agent Development Environment (ADE) purpose-built for running and orchestrating AI coding agents. Unlike traditional IDEs, it lets you launch multiple AI command-line interface (CLI) agents—such as Claude Code, Codex, Gemini, and OpenCode—at the same time, each working in its own isolated git worktree.

That parallel setup means you can multi-task across branches, test competing solutions, and review AI outputs efficiently without waiting on one agent to finish before starting another. Everything happens in a single workspace, so switching contexts becomes effortless.

The environment includes Ghostty-inspired WebGL terminals for smooth, fast performance, an embedded Chromium browser for Design Mode feedback, native GitHub and Linear integration, and a built-in editor—giving you the tools to move from idea to reviewed code in one place.
