There are over one trillion SQLite databases in active use

SQLlite has also got probably the most well-tested code of conduct of any open source project in the world (aside from the other open source projects which use this CoC) https://sqlite.org/codeofethics.html

I also like this page of the docs: "SQLite as an application file format": https://www.sqlite.org/appfileformat.html

In the past, I've used it as a file format for an online application. Users often wanted to download bits and bobs of data from the app, not to view it or edit it on their desktop, but more as backups or to share a particular configuration Previously we'd used a json+zip pair, but the lack of enforced schema became a problem. Switching over to a gzipped sqlite db with a "custom" file extension worked incredibly well

Man i love SQLite. I hate that one of my professors in university was an idiot that didn't really know anything he was talking about told us on many occasions that SQLite was just a toy database that wasn't useful in "real programs". His wrong opinion was ingrained in my mind until i started working as an Android Dev. Now i can only praise the work and the incredible software that SQLite really is.
