`FastAPI`は実際には`Starlette`のサブクラスです。したがって、Starletteをすでに知っているか使用している場合は、ほとんどの機能が同じように機能します。

**FastAPI**を使用すると、以下のような、**Starlette**のすべての機能を利用できます（FastAPIはStarletteを強化したものにすぎないため）:

* 見事なパフォーマンス。<a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank"> **NodeJS**および**Go**に匹敵する、最速のPythonフレームワークの1つです。</a>

* **WebSocket**のサポート
* **GraphQL**のサポート
* プロセス内バックグラウンドタスク
* 起動およびシャットダウンイベント
* `httpx`に基づいて構築されたテストクライアント
