msgspec - a fast & friendly JSON/MessagePack library

• msgspec

  31 1,939 8.3 Python

  A fast serialization and validation library, with builtin support for JSON, MessagePack, YAML, and TOML

I wrote this for speeding up the RPC messaging in dask, but figured it might be useful for others as well. The source is available on github here: https://github.com/jcrist/msgspec.

• pydantic

  167 19,167 9.8 Python

  Data validation using Python type hints

  

It's the serialization library I've always wanted for Python - some of the developer ergonomics of Pydantic (type checking, mypy/pyright integration, rich typing support), but without any of the performance costs.
