Overview

Orca is an AI Orchestrator and Agent Development Environment (ADE) for running a fleet of parallel coding agents from a single seat. It fans one prompt across multiple agents — Codex, Claude Code, OpenCode, or Pi — each isolated in its own git worktree, so results can be compared and the winner merged. Shipped as a desktop app (macOS, Windows, Linux) with a mobile companion, it uses the developer's own model subscriptions rather than reselling compute.

Key Features

  • Parallel worktrees that run multiple agents concurrently on isolated git worktrees for the same repository, with diff comparison and merge.
  • Mobile companion app (iOS and Android) to monitor agents, receive completion notifications, and send follow-ups from anywhere.
  • Ghostty-class terminal splits with WebGL rendering, infinite splits, and scrollback that survives restarts.
  • Design Mode that clicks any UI element in an embedded Chromium window and injects its HTML, CSS, and a cropped screenshot into the agent prompt.
  • Native GitHub and Linear integration to browse PRs, issues, and boards, open worktrees from tasks, and review without context switching.
  • SSH worktrees to run agents on remote machines with full file editing, git, terminals, auto-reconnect, and port forwarding.

Use Cases

  • Running several coding agents in parallel on the same task and merging the best result.
  • Steering long-running agent sessions from a phone while away from the desk.
  • Frontend work where Design Mode feeds live UI context straight into the agent.
  • Coordinating agent-driven PR and issue workflows against GitHub and Linear boards.

Technical Details

  • Desktop app for macOS, Windows, and Linux, plus iOS and Android mobile companions.
  • Bring-your-own-subscription model — Orca drives existing Codex, Claude Code, OpenCode, and Pi accounts rather than proxying model access.
  • Git-worktree-based isolation per agent for safe parallel execution within one repo.
  • Embedded Chromium for Design Mode and a Ghostty-class terminal emulator for in-app shells.
  • YC-backed project, MIT-licensed source.
