Quite OK Image is now my favorite asset format
> You'd probably get even better results by using PNG's filters instead of QOI
Did anybody ever try this? It would be quite interesting and does not seem too difficult.
The only thing I could find is https://github.com/catid/Zpng which does not use the normal PNG filtering.

Google Chrome Is Already Preparing To Deprecate JPEG-XL (~3x smaller than JPEG, HDR, lossless, alpha, progressive, recompression, animations)
Also, Chris Taylor published an experimental PNG library with Zstd hardwired in.

QOI: Lossless Image Compression in O(n) Time
- I feel like the benchmark suite is lacking. For better overview you probably should include libpng results with max compression level and lowest compression level. Lossless modes of AVIF and WEBP would be nice. (also could throw similar project to yours like https://github.com/catid/Zpng) Not saying the benchmark is bad, but IMHO doesn't paint the full picture. From quick test I got significantly better compression on libpng, ofc in expense of time, but you didn't optimize it for speed either. So we have some results, but they are not really representative imho.
What are some alternatives?
When comparing qoi and Zpng you can also consider the following projects:
qoi - A rust implementation of the “Quite OK Image” format for fast, lossless image compression
qoi - The “Quite OK Image Format” for fast, lossless image compression
