Typing stubs for psutil
Decision gist · record as of 2026-08-14
Yes, if you use psutil and run a type checker. It is a lightweight, actively maintained stub package with no runtime dependencies and permissive licensing. Install it alongside psutil to get accurate type hints during development. No reason not to if you are already using a type checker.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; type checking requires a compatible type checker like mypy 2.1.0 or pyright 1.1.409.
- Low friction installation with no runtime dependencies.
- Maintained as part of the typeshed project with active updates; last release 88 days ago.

What it is and what it does
types-psutil is a type stub package that provides type annotations for psutil, the system and process monitoring library. It allows static type checkers—mypy, pyright, and others—to understand and validate code that imports and uses psutil, catching type errors at development time rather than runtime.
The package is maintained as part of typeshed, the standard repository of type stubs for the Python ecosystem. This version targets psutil 7.2.2 and has been tested with mypy 2.1.0 and pyright 1.1.409. Installation adds no runtime overhead; it only affects type checking. It requires Python 3.10 or later.
Use it for
- Enable mypy or pyright to type-check code that calls psutil functions for CPU, memory, or process information.
- Catch incorrect argument types or missing attributes when working with psutil.Process or psutil.sensors in an IDE with inline type checking.
- Maintain type safety in system administration or monitoring scripts that rely on psutil's API.
- Integrate psutil into a larger typed codebase without losing type information at module boundaries.
