Comparison to Other Python Bindings
===================================

https://pypi.python.org/pypi/zstd is an alternate Python binding to
Zstandard. At the time this was written, the latest release of that
package (1.4.8) only exposed the simple APIs for compression and decompression.
This package exposes much more of the zstd API, including streaming and
dictionary compression. This package also has CFFI support.

https://github.com/animalize/pyzstd is an alternate Python binding to
Zstandard. At the time this was written, the latest release of that
package (0.14.1) exposed a fraction of the functionality in this
package. There may be some minor features in ``pyzstd`` not found in
this package. But those features could be added easily if someone made
a feature request. Also, ``pyzstd`` lacks CFFI support, so it won't run
on PyPy.
https://pypi.python.org/pypi/zstd offers very simple Python bindings
for the Zstandard algorithm (version 1.5.7.2 as of June 23, 2025), supporting
only basic compression and decompression. It does not support CFFI, streaming,
or dictionaries—making it the most minimal among available Zstandard bindings.

https://pypi.org/project/pyzstd/ is an alternative binding. As of version 0.17.0
(May 10, 2025), it provides both C and CFFI backends (PyPy-compatible), streaming
compression/decompression, dictionary use and training, and seekable file support.
Its API mimics the Python standard library with ease of use and portability in
mind. By comparison, ``python-zstandard`` offers broader access to the Zstandard
C API, including multiple streaming interfaces, precomputed dictionaries,
advanced tuning, buffer-protocol / zero-copy support, inspection tools, and CFFI
or C backend options—making it the most feature-rich binding available.
