Agent Development Environment 1

Open-source Agent Development Environment for parallel AI coding agents. Orca is an open-source, cross-platform Agent Development Environment (ADE) specifically designed for running and orchestrating AI coding agents. Unlike traditional IDEs, Orca allows developers to run multiple AI command-line interface (CLI) agents—such as Claude Code, Codex, Gemini, and OpenCode—simultaneously in isolated git worktrees. This parallel setup enables users to multi-task across branches, test solutions, and review AI outputs efficiently within an environment featuring Ghostty-inspired WebGL terminals, an embedded Chromium browser for Design Mode feedback, native GitHub/Linear integration, and an editor.
