## 代替手段

数年前から、私は複雑な要件を持つAPI (機械学習、分散システム、非同期ジョブ、NoSQLデータベースなど) を作成しており、いくつかの開発者チームを率いています。

その一環で、多くの方法を調査し、テストし、利用する必要がありました。

**FastAPI** の歴史は、その前身の歴史が大部分を占めています。

[代替ツールから受けたインスピレーションと比較](alternatives.md){.internal-link target=_blank}のセクションでこう述べています:

**FastAPI**は、代替ツールのこれまでの働きがなければ存在しなかったでしょう。

以前に作られた多くのツールが、作成における刺激として役立ってきました。
