The app provides a native macOS environment for running multiple Claude Code (or other) agent sessions side by side in a single window. Each pane operates as an independent terminal powered by SwiftTerm, allowing users to launch as many sessions as needed without relying on Electron or web views. The interface automatically tiles panes, supports splitting and maximizing, and restores the previous layout on relaunch.

A built‑in command palette gives keyboard‑first access to actions such as creating new panes, switching themes, and toggling broadcast mode, where input typed once is sent to all active panes simultaneously. Agent mode queues tasks for the agents, displaying a live timeline of reads, edits, and commands as they are processed in real time.

The application is written in Swift, targeting macOS 13+ and leveraging stream‑json for communication with Claude Code. Optional prompt compression via the wren tool reduces token usage while preserving intent. The software is offered as a free, experimental download with lifetime updates and no subscription model.
