This approach works by storing the actual SQLite binary files in Git and then using a custom "diff" configuration to dump each file as SQL and compare the result.

It's a neat trick, but storing binary files like that in Git isn't as space efficient as using a plain text format.

I built my own tooling to solve this problem: https://datasette.io/tools/sqlite-diffable - which outputs a “diffable” copy of the data in a SQLite database, precisely so you can store it in Git and look at the differences later.

I’ve been running that for a couple of years in this repo: https://github.com/simonw/simonwillisonblog-backup - which provides a backup of my blog’s PostgreSQL Django database (first converted to SQLite and then dumped out using sqlite-diffable).

Here’s an example diff: https://github.com/simonw/simonwillisonblog-backup/commit/72...
