The use case and revenue doesn’t have to be contradictory, I guess? What do you mean by “serious work”? iOS and macOS and their bundled apps use SQLite in a lot of places and Apple generated, idk, at least 9 digits in revenue last year. It sounds like you expect SQLite to excel in all use cases including high concurrency/resiliency web services where traditional heavyweight DBMSes like MySQL and PostgreSQL typically stand out, but that’s far from the truth. The authors of SQLite clearly carve out when you should use it (https://www.sqlite.org/whentouse.html) and it’s clearly succeeding in what it’s good at.

With that said, lots of big firms successfully use SQLite in desktop and web offerings as well: https://www.sqlite.org/famous.html
