Typing stubs for futures
Decision gist · record as of 2026-08-14
Yes, if you use a static type checker with code that imports from futures or concurrent.futures. It is a lightweight, permissive-licensed stub package with no dependencies and active upstream maintenance. Install it as part of your development environment to catch type errors early. If you do not use type checking, it provides no value.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with a pure-Python wheel distribution.
- Maintenance is active with recent repository activity, though the package itself has not been released since 2022-01-27.

Verify before relying
pip install types-futures
# Then use in your code with a type checker:
from concurrent.futures import ThreadPoolExecutor
executor = ThreadPoolExecutor(max_workers=2)
# Type checker now understands ThreadPoolExecutor's interface- Whether this stub package is still synchronized with the current futures API or if newer versions exist elsewhere
- Compatibility with modern type checkers and their evolving stub resolution mechanisms
What it is and what it does
types-futures is a PEP 561 type stub package that provides type information for the standard library's futures module. It allows static type checkers—mypy, PyCharm, pytype, and similar tools—to understand the types and signatures of futures classes and functions when analyzing your code. The stubs are maintained as part of the typeshed project and are generated from its repository.
This package contains no runtime code; it exists solely to improve the type-checking experience. If you use a type checker and work with concurrent.futures or the futures package, installing this stub package will enable your checker to catch type errors and provide better IDE autocompletion. It has no runtime dependencies and installs as a lightweight wheel.
Use it for
- Enable mypy or pyright to type-check code that uses ThreadPoolExecutor or ProcessPoolExecutor
- Get IDE autocompletion and type hints for futures module classes in development environments
- Validate callback signatures and return types in concurrent.futures workflows
- Ensure type safety in async or concurrent code before runtime execution
