Overview

Armin Ronacher created Flask, Jinja2, Click, Werkzeug, and many other foundational Python libraries. His approach: pragmatic minimalism, explicit behavior, and composable design. Flask's success proves that "micro" can be mighty.

Core Philosophy

"Explicit is better than implicit."

"Simple things should be simple, complex things should be possible."

"We're all consenting adults here."

Ronacher believes in trusting developers with power and flexibility, while providing sensible defaults and clear documentation.

Design Principles

  1. Explicit Over Implicit: Never do magic behind the scenes. Make behavior visible.
