FastAPI 是一個現代、快速（高效能）的 Web 框架，用於以 Python 並基於標準的 Python 型別提示來構建 API。

主要特點包含：

* **快速**：非常高的效能，可與 **NodeJS** 和 **Go** 相當（歸功於 Starlette 和 Pydantic）。[最快的 Python 框架之一](#performance)。
* **極速開發**：開發功能的速度可提升約 200% 至 300%。*
* **更少的 Bug**：減少約 40% 的人為（開發者）錯誤。*
* **直覺**：具有出色的編輯器支援，處處都有 <dfn title="也稱為：自動完成、自動補全、IntelliSense">自動補全</dfn>。更少的偵錯時間。
* **簡單**：設計上易於使用與學習。更少的讀文件時間。
