Bearblog is a service, not a static site generator one can use like Hugo.

From the Bearblog GitHub:

> Bear Blog has been built as a platform and not as an individual blog generator. It is more like Substack than Hugo. Due to this it isn't possible to individually self-host a Bear Blog.

Jekyll would an alternative for Hugo.

Whoops. My mistake for only reading HN headlines and extrapolating. OP, please disregard this recommendation.
