概要

数百のサービスをビジュアルキャンバス上で連携させるツールで、近年はそのフロー内にLLMエージェントを組み込む用途が増えています。最初に確認すべきはライセンスです。OSI承認のオープンソースではなく、Sustainable Use Licenseによるソース公開型にあたります。社内利用やセルフホストは可能ですが、ホスティングサービスとして再販することは認められていません。

n8nで何ができますか？

ローカルでエディタを起動 — npx n8nですぐに立ち上がり、docker.n8n.io/n8nio/n8nのイメージにn8n_dataボリュームを割り当てる方法でもポート5678でキャンバスを開けます。
フローの中にエージェントを置く — 1500以上の連携ノードを並べた同じキャンバス上で、ツール呼び出しや条件分岐、人間の承認を挟んだ複数ステップのエージェントを1ステップとして組み込めます。
公開済みのフローから始める — READMEは1500以上の連携ノードと併せてn8n.io/workflowsの9,000件超のワークフローテンプレートを案内しており、白紙のキャンバスではなく既存のフローを土台にできます。
足りない処理はコードで書く — ノード内でJavaScriptとPython、npmパッケージを利用でき、ビジュアル構築では表現しきれない処理を補えます。

What does n8n mean?

Short answer: It means “nodemation” and is pronounced as n-eight-n.

Long answer: “I get that question quite often (more often than I expected) so I decided it is probably best to answer it here. While looking for a good name for the project with a free domain I realized very quickly that all the good ones I could think of were already taken. So, in the end, I chose nodemation. ‘node-’ in the sense that it uses a Node-View and that it uses Node.js and ‘-mation’ for ‘automation’ which is what the project is supposed to help with. However, I did not like how long the name was and I could not imagine writing something that long every time in the CLI. That is when I then ended up on ‘n8n’.” - Jan Oberhauser, Founder and CEO, n8n.io
