**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]].
