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.

So you want to write a GUI framework (2021)
( https://github.com/elcritch/cssgrid )
However, text input is hard and tedious! Then you ideally would need to handle the different keybindings for each OS. You also loose any plugins the OS'es provide. Not to mention the lack of accessibility.
I recall reading that browsers shim out to native OS text fields and wonder how that's done. It really seems like the best approach for small GUI libraries to enabled first class text input.

Declarative User Interfaces with constraints-based layout engine for Python
Nucleic also makes Kiwi one of the fastest Cassowary Constraint implementations. It is very useful for implementing custom GUIs as it can make building internal component layouts and general layout systems fairly straightforward and it’s very performant.
I highly encourage taking a look at it and it has also been ported to a wide range of language.
I’m using Nim kiwi with my own GUI library now. I’ll have to take a peak at how enaml is using kiwi for its layouts.

Luau Goes Open-Source
If any of the Luau devs are watching this, please flesh out the metamethods. I'd switch almost everything to Luau if they were improved.
They're the biggest PITA right now as designed in PUC-Rio, and I see that while you've improved upon __eq, other metamethods are still lacking.
In PUC-Rio, boolean equality operators FORCE a boolean result, regardless of what you return. Ideally they would allow returning any result type, which then can be coerced to boolean later (e.g. by an `if` statement), just like the arithmetic operators do.
Further, `__neq`, `__ge` and `__gt` do not exist. They should.
The lack of a proper metamethod design means that binding to e.g. Kiwi[0] is impossible without some incredibly fugly hacks. It has been a long-standing annoyance with Lua in an otherwise beautiful little scripting language (that I use frequently).
This looks quite nice - lots of attempts in this space but nothing that attempts to match Lua to this degree.
