Typing stubs for cffi
Decision gist · record as of 2026-08-14
Yes, if you use cffi and want static type checking. Install it as a dev dependency alongside cffi to enable type checkers to validate your C bindings. No runtime overhead; purely a type-checking aid. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.10.
- Only useful when used alongside a type checker (mypy, pyright, etc.) in your development workflow.
- Low friction install as a pure-Python wheel.

What it is and what it does
types-cffi is a type stub package that bridges the gap between cffi and Python's static type checkers. It provides type annotations for the cffi library so that tools like mypy and pyright can understand and validate code that uses cffi to call C functions from Python. The stubs are maintained as part of the typeshed project and target cffi version 2.0.*.
This package is not a runtime dependency of your application—it's a development-time tool that helps catch type errors during static analysis. You install it alongside cffi, and your type checker automatically uses it when analyzing code. It requires Python >=3.10 and has been tested with mypy 2.1.0 and pyright 1.1.409.
Use it for
- Enable mypy or pyright to type-check code that calls cffi functions and classes
- Catch type errors in cffi bindings before runtime in CI/CD pipelines
- Provide IDE autocomplete and type hints for cffi APIs in editors that support type stubs
