Prometeu is a free, open-source desktop app for Mac and Linux that lets developers run Claude Code, Codex, Cursor CLI, and Antigravity coding agents in parallel, each isolated in its own git worktree. It provides a unified workspace combining conversations, file views, terminals, and browser previews alongside each agent session. Users can review diffs, leave inline feedback, and selectively stage and commit changes before merging. An optional Cloud tier adds team sharing, shared tool catalogs, and mobile browser access for following and directing agents remotely.
