AltWindow
Live companion windows for Claude Code.
A native macOS app that renders independently managed windows — Activity, Tasks, and more — live from Claude Code's hook events. Your Claude Code client stays exactly as it is: no embedding, no patching. Just real native UI with live state, in its own window.
