This project provides Python bindings for interfacing with the
`Zstandard <http://www.zstd.net>`_ compression library. A C extension
and CFFI interface are provided.

The primary goal of the project is to provide a rich interface to the
underlying C API through a Pythonic interface while not sacrificing
performance. This means exposing most of the features and flexibility
of the C API while not sacrificing usability or safety that Python provides.

The canonical home for this project is

## AI interpretation — verify before relying

Python bindings for the Zstandard compression library, offering both C extension and CFFI interfaces to compress and decompress data with high performance and access to the full Zstandard C API.

Verdict: Production-stable, actively maintained compression library with no known vulnerabilities, broad platform coverage via prebuilt wheels, and permissive licensing. Medium install friction is offset by comprehensive wheel distribution and strong maintenance signals (active status, recent commits, top-1000 popularity).
