Our verdict

Fast and private, but the interface fights you

Patchwork diffs JSON entirely in your browser, so nothing leaves your machine, and it handled a 20 MB file without stalling.

The interface hides useful options behind unlabeled icons, and it took us a while to find ignore-key paths. Worth watching as the design matures.
