Orca

Orca is an open-source agent development environment (ADE) that lets developers run multiple CLI coding agents — like Claude Code, Codex, and OpenCode — side by side, each isolated in its own git worktree, with terminals, diffs, a Chromium browser, and a CLI in one desktop app. It's built for engineers who already rely on terminal-native agents and whose bottleneck is supervising parallel work rather than a single autocomplete assistant. Its key differentiator is treating a fleet of parallel agents as the default workflow — bring your own subscriptions, fan one prompt across several agents, and merge the winner — plus a mobile companion for monitoring agents on the go.
