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.

The Near-Lossless Image Formats Using Ultra-Fast LZ Codecs
It's important to notice that ZPNG beats virtually all QOI variants, as discovered in: https://github.com/nigeltao/qoir

Hello, PNG
But most platforms these days have some form of CRC32 "acceleration". Adler32 is easy to compute so I'm even less concerned there.
I spent a bunch of time optimising the code in [fpnge](https://github.com/veluca93/fpnge), which is [often notably faster than fpng](https://github.com/nigeltao/qoir/blob/5671f584dcf84ddb71e28d...), yet checksum time is basically negligible.
Having said that, the double-checksum aspect of PNG does feel unnecessary.

Quite OK Image is now my favorite asset format
* AFAIK it does this while beating the original QOI in terms of speed AND efficiency
Lots of benchmarks in: https://github.com/nigeltao/qoir
QOIX
QOIX is my very own version that adds:

What are some alternatives?
CompactGUI - Transparently compress active games and programs using Windows 10/11 APIs
tinf - Tiny inflate library (inflate, gzip, zlib)
libdeflate - Heavily optimized library for DEFLATE/zlib/gzip compression and decompression
fpng - Super fast C++ .PNG writer/reader
ZLib - A massively spiffy yet delicately unobtrusive compression library.
figlet-fonts - my collection of figlet / toilet ascii art fonts
EightThirtyTwoDemos - Demo projects for the EightThirtyTwo CPU
fpnge - Demo of a fast PNG encoder.

Zpng - Better lossless compression than PNG with a simpler algorithm
