### Deploy your app (optional)

You can optionally deploy your FastAPI app to [FastAPI Cloud](https://fastapicloud.com), go and join the waiting list if you haven't. 🚀

If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command.

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...
