Your agents,
under one roof.

tulou brings Claude Code, Codex, OpenCode and Grok into one Windows app. Each agent gets its own room, they hand work to each other and review each other’s changes, and you decide what gets merged.

Several agents.
One window.

The tulou window: three agents working in separate workspaces of the acme-notes repository, each in its own pane. — A real capture of tulou on a demo repository.

Rooms
Each agent works in its own workspace on a Git worktree, side by side in one window.
Handoffs
Pass a task from one CLI to another with its context, without copying anything by hand.
Reviews
A second agent reviews a frozen checkpoint before anything reaches your main branch.

Why tulou?

In Fujian, a tulou (土楼) is a round earthen house where many families live in rooms around one shared courtyard.

The app works the same way: your agents keep their own rooms, and their work meets in the courtyard, your main branch.
