TL;DR
A unified development environment (ADE) for running and managing multiple AI coding agents in parallel.
Key features
Parallel Worktrees: Fan a single prompt across multiple agents and compare their results in isolated Git worktrees.
Mobile Companion: Monitor agent progress from your phone, receive notifications on completion, and send follow-up instructions remotely.
Design Mode: Click any UI element in the embedded browser to send its HTML, CSS, and a screenshot directly into an agent's prompt.
Advanced Terminal: A high-performance, WebGL-based terminal with infinite splits and scrollback that survives restarts.
When to use it
When you want to compare the performance of multiple AI coding agents under identical conditions.
When you want to parallelize a task across several agents to accelerate development.
When you need to flexibly manage agent tasks while moving between desktop and mobile.
