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.

Show HN: Micro LZMA decoder (x86 assembly code golf)
Crinkler [1] is a popular compressor-linker for 1--8 KB demos and its decompressor (partially embedded in a PE header) is probably around 1--200 bytes. Later efforts like oneKpaq [2] also have a comparable decompressor size.
If you don't mind a shameless plug and a slightly larger decompressor (about 500 bytes in JS) for better compression, my Roadroller [3] might fit the bill as well.

Game Boy Wordle clone: How to compress 12972 five-letter words to 17871 bytes
Roadroller [1] is probably a borderline general purpose compression algorithm, and with some automatic parameter tuning it results in 12,170 bytes estimated [2], at the expense of a lot of memory. "Estimated" because the algorithm was originally meant to be recompresssed in a ZIP file, so it doesn't bother to generate the smallest JS file in terms of uncompressed size (yet).
[1] https://lifthrasiir.github.io/roadroller/ (the exact parameters: golf.horse dataset; input mode text; action write to document; # contexts 12 with 12,15,49,50,70,79,96,97,131,154,292,353; pollute the global scope; max memory usage 150 MB; precision 16; learning rate 1333; model max count 11; model base divisor 14; dynamic model flags -1; # abbreviations 64)

Cat Goric: Escape from the Warp Chamber - Post-Mortem
And compressed final code even more with Roadroller (reduced 1.3 KB in the zip). And used ECT to recompress the zip (reduced 300 KB).

Q1K3
I'm honored that Q1K3, in addition to many other entries to js13kGames 2021, is compresed with Roadroller [1], which is the reason that its source code is basically a random-looking string plus some bit of JS code.

SectorC: A C Compiler in 512 bytes
Now they just need to port something like oneKpaq to 16 bit or maybe something from the extremely tiny decompressor thread [1], just to test compression level to get an idea kpaq on its quickest setting(taking minutes instead of what could be days on its highest) reduced SectorC to 82.81% of its size, of course adding the 128 bit stub knocked it to 677 bytes. It would be interesting to try it on the slowest takes day to bruteforce setting, but I'm not going to attempt that.
Some of the compressors in that forum thread since they are 32 bytes and such, might find it easier to get net gains.
