# FastAPI CLI { #fastapi-cli }

**FastAPI CLI** ist ein Kommandozeilenprogramm, mit dem Sie Ihre FastAPI-App bereitstellen, Ihr FastAPI-Projekt verwalten und mehr.

Wenn Sie FastAPI installieren (z. B. mit `pip install "fastapi[standard]"`), wird ein Package namens `fastapi-cli` mitgeliefert, das den Befehl `fastapi` im Terminal bereitstellt.

Um Ihre FastAPI-App für die Entwicklung auszuführen, können Sie den Befehl `fastapi dev` verwenden:

<div class="termy">

# FastAPI CLI { #fastapi-cli }

**FastAPI CLI** is a command line program that you can use to serve your FastAPI app, manage your FastAPI project, and more.

When you install FastAPI (e.g. with `pip install "fastapi[standard]"`), it includes a package called `fastapi-cli`, this package provides the `fastapi` command in the terminal.

To run your FastAPI app for development, you can use the `fastapi dev` command:

<div class="termy">

```console

If you don't want to include the `standard` optional dependencies, you can install with `pip install fastapi` instead of `pip install "fastapi[standard]"`.

### Without `fastapi-cloud-cli`

If you want to install FastAPI with the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`.

### Additional Optional Dependencies
