Seine Schlüssel-Merkmale sind:

* **Schnell**: Sehr hohe Leistung, auf Augenhöhe mit **NodeJS** und **Go** (Dank Starlette und Pydantic). [Eines der schnellsten verfügbaren Python-Frameworks](#performanz).

* **Schnell zu programmieren**: Erhöhen Sie die Geschwindigkeit bei der Entwicklung von Funktionen um etwa 200 % bis 300 %. *
