About urllib3

urllib3 is a powerful, user-friendly HTTP client for Python. Much of the Python ecosystem uses urllib3. urllib3 brings many critical features that are missing from the Python standard libraries:

  • Thread safety.
  • Connection pooling.
  • Client-side SSL/TLS verification.
  • File uploads with multipart encoding.
  • Helpers for retrying requests and dealing with HTTP redirects.
  • Support for gzip and deflate encoding.
  • Proxy support for HTTP and SOCKS.
  • 100% test coverage.

urllib3 is used by many popular Python packages, like Requests and Pip. Chances are, if you're writing code in Python, you might be using urllib3.

urllib3 and the maintainers of thousands of other packages are working with Tidelift to deliver one enterprise subscription that covers all of the open source you use. If you want the flexibility of open source and the confidence of commercial-grade software, this is for you.

Check out this blog post about how Tidelift worked with the maintainers of urllib3 to create a coordinated security vulnerability disclosure to help Tidelift subscribers avoid zero-day fire drills.

You can learn more on the urllib3 project repo.



"Tidelift has made the process of offering a comprehensive vulnerability disclosure process simple for the urllib3 team. This makes delivering secure code and responding quickly to vulnerabilities easy even for a small team."

- Seth Larson, urllib3 co-maintainer
