I originally built this for myself because I didn't like waiting around for Claude Code to finish and I didn't want to mess with a bunch of terminal windows to use worktrees so I built a GUI. Then I started adding more features, diff view, script running, and more and my team and I decided it needed to be shared as an open source project.

Excited to hear what the HN community thinks.
