What is n8n?
n8n is a workflow automation tool you can run on your own server or use as a hosted service. It has become a common choice for building AI agents because the LLM steps are first-class rather than bolted on.
What it does well
Automations that must keep data inside your own infrastructure, and agent-style workflows where a model decides which tool to call next.
Who should use it
Teams with someone technical, agencies building automations for clients, and businesses with data residency requirements.
Who should not use it
A small business with no technical support. The self-hosted saving is not a saving if nobody can maintain it.
