I use Fossil extensively for all my personal projects and find it superior for the general case. As others said it’s more suited for small projects.

I also use Fossil for lots of weird things. I created a forum game using Fossil’s ticket and forum features because it’s so easy to spin up and for my friends to sign in to.

At work we ended up using Fossil in production to manage configuration and deployment in a highly locked down customer environment where its ability to run as a single static binary, talk over HTTP without external dependencies, etc. was essential. It was a poor man’s deployment tool, but it performed admirably.

Fossil even works well as a blogging platform.
