The built in DB makes this very interesting to me. Although I would prefer sqlite. The low LOC count is nice to know.

Minimilism is something that is hard to get right on the web. The cliche is people avoid django because it is too complex then hand build all its features anyway over time!

However some jobs are minimal esp. internal dashboards so there is a place for it. You may find fasthtml which is also minimal interesting.

Curious: why Java and not Go? Go seems more in line with being minimal. Especially for deployment.
