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

A rust binding for the zstd compression library.

Python bindings to the Zstandard (zstd) compression library

Fast In-Memory Data Compression Algorithm (header-only C/C++) 540+MB/s compress, 3000+MB/s decompress, ratio% better than LZ4, Snappy, and Zstd@-1

go wrapper for zstd

zstd format implementation in pure rust

Seekable lossless compression with O(1) random access, built for ultra-fast decode. Faster than LZ4 (40%+ on ARM64), with better ratios. C library, write-once/read-many.

HPCC-Systems Web-Assembly (JavaScript)

⚡An Easy-to-Use and Optimized compression library for .NET that unified several compression algorithms including LZ4, Snappy, Zstd, LZMA, Brotli, GZip, ZLib, and Deflate. This library aids in Improving Performance by Reducing Memory Usage and Bandwidth Usage. Along with a greate Performance Benchmark between different compression algorithms.
