Orca is a desktop app for running several coding agents in parallel, each in its own git worktree, and tracking them in one place. It runs any CLI agent that works in a terminal, including Claude Code, Codex, OpenCode, Pi, Gemini, and Cursor CLI, on your own subscriptions. You can fan one prompt out to several agents, compare their results, and merge the one you want.
Around the agents it bundles the rest of the development loop: terminal splits with WebGL rendering and scrollback that survives restarts, a VS Code-based editor, diff review with comments sent back to the agent, and native GitHub and Linear views for pull requests, issues, and project boards. A design mode in a real Chromium window sends a clicked element's HTML, CSS, and a cropped screenshot into the agent's prompt.
Worktrees can also live on a remote machine over SSH with file editing, git, and terminals. Agents can drive Orca themselves through its CLI, which creates worktrees, takes snapshots, and clicks and fills UI, and a computer use mode lets them operate desktop apps. The desktop app runs on macOS, Windows, and Linux, and an iOS and Android companion pairs with it through a relay to notify you when an agent finishes and to send follow-ups.
