## FastAPI Cloud { #fastapi-cloud }

**<a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>** wurde vom selben Autor und Team hinter **FastAPI** entwickelt.

Es vereinfacht den Prozess des **Erstellens**, **Deployens** und **Zugreifens** auf eine API mit minimalem Aufwand.

Es bringt die gleiche **Developer-Experience** beim Erstellen von Apps mit FastAPI auch zum **Deployment** in der Cloud. 🎉
