Static type checkers

• basedmypy - Based static typing with baseline functionality.
• basedpyright - Pyright fork with improvements to VSCode support and various other fixes.
• mypy - Optional static typing (PEP 484).
• pyanalyze - Extensible static analyzer and type checker.
• PyCharm - IDE for Professional Developers.
• pylyzer - A fast static code analyzer & language server for Python, written in Rust.
• pyre - Performant type-checker.
• pyright - Fast type checker meant for large Python source bases. It can run in a “watch” mode and performs fast incremental updates when files are modified.
• pytype - Tool to check and infer types - without requiring type annotations.

Dynamic type checkers

• beartype - Unbearably fast O(1) runtime type-checking in pure Python.
• pydantic - Data parsing using Python type hinting. Supports dataclasses.
• pytypes - Provides a rich set of utilities for runtime typechecking.
• strongtyping - Decorator which checks whether the function is called with the correct type of parameters.
• typedpy - Type-safe, strict Python. Works well with standard Python.
• typeguard - Another one runtime type checker.
• typical - Data parsing and automatic type-coercion using type hinting. Supports dataclasses, standard classes, function signatures, and more.
• trycast - Parse JSON-like values whose shape is defined by typed dictionaries (TypedDicts) and other standard Python type hints.

Stub packages

• asgiref - ASGI specification, provides asgiref.typing module with type annotations for ASGI servers.
• boto3-stubs - Stubs for boto3.
• botostubs - Gives you code assistance for any boto3 API in any IDE.
• celery-types - Type stubs for Celery and its related packages django-celery-results, ampq, kombu, billiard, vine and ephem.
• django-stubs - Stubs for Django.
• djangorestframework-stubs - Stubs for DRF.
