    Personally, I think it's great to have many projects solving the same problem and pushing each other further. Although the differences between the faster validations are small, the older ones were quite slow. This will save unnecessary CPU cycles, making it eco-friendly. And now the bar will be even higher with a Rust version, which is really great.

    [0]Maat is 2.5 times faster than Pydantic on their own benchmark, as stated in their readme.

    Since validation is written as dictionaries its possible to store the validations in caching db such as Redis.

    And since its simple its easy to extend for anyone use case.

    Benchmarks of pydantic has Maat around twice as Pydantic.
