Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Topiary: A code formatting engine leveraging Tree-sitter
It's ironic that just as the excellent https://github.com/ocaml-ppx/ocamlformat is seemingly closing in on 1.0 after ~4 years of development, here comes the implication that it's not good enough.

Is there any way to format mll/mly files?
Ocamlformat does not - issue has been open since 2019

Topiary: A code formatting engine leveraging Tree-sitter
Yes. It's typically a fair bit slower than a hand-coded parser. The idea sounds great until you're working on a codebase with 2 million LOC. At that point, the speed of a cold parse is most important, whereas TS is designed for fast re-parsing of a single file. These aren't great numbers but the Rust TS parser is reportedly 2x slower than rustc's https://github.com/tree-sitter/tree-sitter-rust. It's no surprise that you just use the faster option if it's convenient.
