Typing stubs for urllib3
Decision gist · record as of 2026-08-14
Yes, if you use urllib3 and rely on static type checking. The package is actively maintained, has no security vulnerabilities, and installs without friction. However, if you use urllib3 2.0.0 or later, which includes native type annotations, this package is redundant.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction installation with no runtime dependencies.
- Maintenance is active, though the latest release was 2023-07-20; note that urllib3 2.0.0+ includes its own type annotations, making this package unnecessary for newer urllib3 versions.

Verify before relying
pip install types-urllib3
import urllib3
http = urllib3.PoolManager()
response = http.request('GET', 'https://example.com')- Whether partial stub coverage is sufficient for your codebase's urllib3 usage patterns.
- Compatibility with urllib3 versions 2.0.0+ where native type annotations are now included.
What it is and what it does
types-urllib3 is a PEP 561 type stub package that provides type annotations for the urllib3 HTTP client library. It allows static type checkers like mypy, pyright, and pytype to understand and validate code that uses urllib3, catching type errors before runtime. The stubs are generated from typeshed and marked as partial, meaning some annotations may be incomplete.
This package is primarily useful for projects using urllib3 versions before 2.0.0, which did not include native type annotations. The package has no runtime dependencies and installs with minimal friction. Maintenance is active with the repository at https://github.com/python/typeshed.
Use it for
- Enable type checking in a project using urllib3 with mypy or pyright.
- Catch type errors in urllib3-based HTTP client code during development rather than at runtime.
- Provide IDE autocomplete and type hints for urllib3 methods in PyCharm or other type-aware editors.
- Validate third-party code that depends on urllib3 in a strictly typed codebase.
