About

Orca is a desktop IDE for developers who run coding agents such as Codex, Claude Code, OpenCode or Pi. Agents can work side by side in separate Git worktrees, letting you compare results and merge changes.

It includes split terminals with persistent scrollback, a code editor and diff comments that can be sent back to an agent. GitHub and Linear integration brings pull requests, issues and project boards into the workspace. An embedded Chromium browser has a Design Mode that sends a selected element’s HTML, CSS and screenshot to an agent.

SSH worktrees support remote agents with file editing, terminals, reconnection and port forwarding. A mobile companion can monitor agents, receive completion notifications and send follow-up instructions.

Orca is free and open source under the MIT license. The macOS builds support Apple silicon and Intel Macs; the Homebrew cask declares macOS 11 or later.
