lizard
Lizard is an efficient compressor with very fast decompression. It achieves compression ratio that is comparable to zip/zlib and zstd/brotli (at low and medium compression levels) at fast decompression speed (by inikep)

uzlib
Radically unbloated DEFLATE/zlib/gzip compression/decompression library. Can decompress any gzip/zlib data, and offers simplified compressor which produces gzip-compatible output, while requiring much less resources (and providing less compression ratio of course).

Stm32-FatFs-Gzip
This project offers a simplified compressor that produces Gzip-compatible output with small resources for microcontrollers and edge computers. He uses the very basic LZ77 compression algorithm and static Deflate Huffman tree encoding to compress / decompress data into Gzip files.
