### What we like

Makes it easy to switch from Git to JJ by exposing the functionality in the GUI (also works with Git repos). Implements core features e.g. undo/redo changes, visual diff of multiple commits, create custom revsets, easy rebasing.

### Tradeoffs

Not open source (undefined plans for commercial license - currently seems to be a side project). Doesn’t support native merges or splitting.
