Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
We haven't tracked posts mentioning serpy yet.

apischema v0.17 - I've developed the fastest typed JSON (de)serialization library, and you can also build your GraphQL schema with it
5 projects | reddit.com/r/Python | 18 Jan 2022
This month, I've released version 0.17, and it's now blazing fast; there is in fact no more comparison with Pydantic, which more than 5x slower (up to 30x in serialization). It's also faster than alternatives like mashumaro or cattrs. (See the quick benchmark result in documentation, and the code)
cattrs – an open source Python library for structuring and unstructuring data

I use attrs instead of pydantic
5 projects | news.ycombinator.com | 26 Aug 2021
Cattrs has some problems with generics  . Dacite and marshmallow-dataclasses don't support generics well either, with some issues around Union types.
They do work well for simple python types but what I'd like to see is guarantee that the serialisation operation is completely reversible and if not raise warning/exception.
What are some alternatives?
marshmallow - A lightweight library for converting complex objects to and from simple Python datatypes.
pydantic - Data parsing and validation using Python type hints
jsons - 🐍 A Python lib for (de)serializing Python objects to/from JSON
Fast JSON schema for Python - Fast JSON schema validator for Python.
Trafaret - Ultimate transformation library that supports validation, contexts and aiohttp.
lupin is a Python JSON object mapper - Python document object mapper (load python object from JSON and vice-versa)
ultrajson - Ultra fast JSON decoder and encoder written in C with Python bindings
PyLD - JSON-LD processor written in Python
RDFLib plugin providing JSON-LD parsing and serialization - JSON-LD parser and serializer plugins for RDFLib
PyValico - Small python wrapper around https://github.com/rustless/valico
