What each one is

The product in its own terms, so the numbers below have context.

mypy

Leader

A type analysis tool for Python that enables code to transition from pure dynamic typing to statically-typed code through annotations, with error detection at check time. Code runs with negligible performance impact and developers can incrementally adopt static types in existing projects.

Independently observed

Qlty

A code quality platform that automatically analyzes pull requests for linting, formatting, security issues, and code coverage with AI-generated fixes. Supports 40+ languages and integrates with GitHub, IDEs, and CI systems.
