Con **FastAPI** obtienes todas las características de **Starlette** (porque FastAPI es simplemente Starlette en esteroides):

* Desempeño realmente impresionante. Es uno <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank"> de los frameworks de Python más rápidos, a la par con **NodeJS** y **Go**</a>.
* Soporte para **WebSocket**.
