Orca: the ADE for orchestrating a fleet of coding agents in parallel
What do you do when Claude Code proposes one solution, Codex a different one, and Gemini a third? The usual move is to pick an agent up front and take whatever it produces. Orca changes that dynamic: it runs all three at once, each isolated in its own git worktree, and lets you compare the results and merge the one that won. It's an open-source ADE (Agent Development Environment)—MIT, by Stably…
Claude Code, Codex, and Gemini each propose different solutions to coding tasks. Rather than choosing a single agent and accepting its output, Orca runs all three simultaneously in isolated worktrees. This open-source Agent Development Environment (ADE), built by Stably AI and MIT licensed, lets you compare the results and merge the best solution.
Orca can orchestrate any CLI agent, from Claude Code, Codex, Gemini to Grok, Cursor CLI, and OpenCode, and over 25 others. Each agent runs in its own isolated worktree with its own terminal, browser, and context. Orca provides a CLI and an orchestration layer with tasks, dispatches, and decision gates to coordinate the fleet of agents.
The tool is available on macOS, Windows, Linux, iOS, and Android, and can be installed via Homebrew or AUR, with daily updates. Orca differs from traditional IDEs and other agent interfaces by focusing on coordinating multiple agents in parallel, rather than just one agent working line by line.
