Werkzeug is a WSGI (Web Server Gateway Interface) utility library for Python that emerged from the Pocoo project. It provides low-level utilities for building web applications and frameworks.

Developed by the Pocoo team led by Armin Ronacher and Georg Brandl, Werkzeug serves as the foundation for Flask and other Python web frameworks. It’s now maintained under the Pallets Projects.
