Open-source Agent Development Environment for parallel AI coding agents

Overview

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.

Short scenarios where Orca tends to shine.

  • Fanning out a single prompt across multiple AI agents to compare and merge the best solution

    Best for Software engineers

  • Running servers, tests, logs, and AI agents side-by-side without stashing or branch juggling

    Best for AI developers

  • Using a mobile companion app to monitor live agent status, check usage, and manage tasks on the go

    Best for DevOps engineers

How it works

Download and install Orca on macOS, Windows, or Linux. Plug in your existing AI subscriptions or CLI tools (like Claude Code or Codex). Create a workspace, spin up multiple agents across isolated git worktrees to handle different tasks, monitor their progress in the split terminal view, or use Design Mode to send UI feedback directly to your agents.
