Orca is a tool that runs various AI coding agents, such as Codex, Claude Code, and OpenCode, simultaneously within a single window. Each agent operates in an independent git worktree, enabling parallel development without code conflicts. It supports a workflow where a single prompt is distributed to multiple agents, allowing users to compare results and select the best code for merging.

Beyond a simple terminal, it integrates the development environment. Features include a high-performance terminal split with WebGL rendering support, a design mode that sends HTML and CSS to agent prompts by clicking UI elements in a real Chromium window, and the ability to view GitHub and Linear issues directly within the app and open worktrees. It also supports running agents on powerful hardware via SSH worktrees on remote servers.

A mobile companion app allows monitoring agent status and sending follow-up instructions from smartphones. It also provides features to drag and drop files to agents in a VS Code-based editor, or annotate AI-generated diffs to request immediate modifications. It is available on macOS, Windows, and Linux desktops, as well as iOS and Android mobile devices, and is released under the MIT license.
