Orca

Run many coding agents in parallel, each in its own worktree

Parallel worktrees

Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.

Bring your own agent CLI

Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.

Integrated browser and design mode

A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.

Terminal, diffs and split panes

Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.
