# Alternativen, Inspiration und Vergleiche

Was hat **FastAPI** inspiriert, ein Vergleich zu Alternativen, und was FastAPI von diesen gelernt hat.

## Einführung

**FastAPI** würde ohne die frühere Arbeit anderer nicht existieren.

Es wurden zuvor viele Tools entwickelt, die als Inspiration für seine Entwicklung dienten.
