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.

Electronic leadscrew, or full CNC?
And it looks like pendant support was 'enabled' last year in grblHAL, but I don't see the "I'm with stupid guide" that I would need to connect it.

General question: Why use an old LPT interface with so many open source controller available?

Budget budget CNC controllers - what's the bottom line?
You might want to look at grblHAL. It is the 32-bit evolution of Grbl. I make a 5 axis breakout board for it based on a Teensy 4.1. It supports step rates up to 400 kHz which allows you a lot of freedom in selecting microsteps and high speed rapids. All in with the Teensy, it costs about $65-70, depending on options. Here is a gallery with a number of machines based on grblHAL. More about grblHAL here. It is actively being developed with people adding features and porting to new processors (RaspBerry Pico is coming).
