SQLite is underrated. I’ve used it for high traffic systems with no issues. If your system has a large number of readers and a small number of writers, it performs very well. It’s not as good for high-concurrency write-heavy use cases, but that’s not common (most apps read far more than they write).
My use case was a DB that was created during the build process, then read on every page load.

Hopefully nobody lands on the same space as another player in Mario Party.
