What is mypy?
Mypy is an optional static type checker for Python that combines the benefits of dynamic and static typing. It enables compile-time type checking with no runtime overhead while allowing gradual migration from dynamic to static typing.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for mypy, not the verdict.
