A collection of optimized pure-Go compression packages including zstandard, S2 (a Snappy replacement), and drop-in replacements for gzip, zip, zlib, flate, and lzw. It offers faster compression/decompression than the Go standard library, with optional assembly acceleration and concurrent stream encoding.

Use cases

• compress data faster than the Go standard library
• read and write zstd compressed streams in Go
• replace gzip/zip/zlib with a faster drop-in
• compress HTTP responses and handle gzipped requests
• high-throughput Snappy-style compression with S2
• parallel gzip compression

When to choose

• you need faster compression or decompression than compress/* in Go
• you want pure-Go zstd without cgo
• you need concurrent or streaming compression in Go services

When to avoid

• you are not using Go
• you need exotic formats like brotli or lz4
• you only need trivial compression where the standard library suffices
