GitHub · Installation · Getting Started · API Reference · Changelog

Stop fighting your type checker — work with it.
optype gives you single-method protocols for every dunder, exact types that reject sneaky subtypes, and typed operators that actually make sense — so you can express what your code really accepts.

Zero dependencies. Works with every modern type checker. Optional NumPy support included. Battle tested.
