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.

Aro: A C compiler written in Zig
For contrast, gforth (a prominent Forth interpreter, by Forth standards) generates+compiles+links binding code in C, at runtime, using the ordinary C toolchain. [0][1][2]
A bit 'out there' you may say, but on the plus side this approach enables handling header files and tidily expressing bindings without the need to implement their own C parser. [2]
