Hm, that claims SQLite is 'never' used for web backends; Bun says it's motivated for use 'at the edge' - first thing I thought of when I read that was Fly.io/Litestream: https://fly.io/blog/all-in-on-sqlite-litestream/

(No idea if there's any relationship between the projects, just makes me think that article's a bit dismissive.)
