urllib3

Tech stack & purpose

urllib3 is a powerful, user-friendly HTTP client library for Python that provides critical features missing from Python's standard libraries, including thread safety, connection pooling, client-side SSL/TLS verification, multipart file uploads, retry and redirect helpers, support for multiple compression encodings, and proxy support for HTTP and SOCKS. The project is written in Python and has been maintained since 2008 by a team of individual maintainers including Illia Volochii, Seth M. Larson, Quentin Pradet, and others, with a strong emphasis on code quality, security, and safety standards. urllib3 is widely used across the Python ecosystem and achieves 100% test coverage.
