I built a python package to run JSON diffs. It is probably the fastest json diff out there (python ecosystem).
Previously I used the well-known package called jsondiff, it is great but when it comes to large json payloads it sucks (badly) :(
I didn't want to implement it in pure Python because eventually it would still be very slow hence I decided to use Zig programming language. Seems like the final product solves my problems with poor performance with large JSON payloads.
