snappy-hs

A pure Haskell implementation of the Snappy compression format.

This library prioritizes portability and simplicity over raw speed. It works reliably across platforms without requiring a C toolchain or dealing with FFI.

Performance

In informal benchmarks, this implementation is roughly 2–3× slower than native Snappy.

When to use

• You want cross-platform Snappy encode/decode with a pure Haskell dependency stack
• You’d rather avoid C FFI and the build/packaging complexity that comes with it

When not to use

• You need maximum throughput (use the native library or an FFI-based binding instead)
