Lesson 1 of 6
Why n8n?
6 min read
Most automation tools are a locked room you rent by the month. n8n is a house you can own — free to run, open to change, and built for AI agents. Why does that matter?
Own it, don't rent it
Most automation tools live on someone else's servers. You rent access, pay per task, and your data flows through their systems. n8n is open-source — the code is public and free — and you can [self-host](glossary://self-hosting) it: run it on your own machine, so the workflows and the data stay with you. Rent a room, or own the house.
Renting is instant and hands-off; owning takes a little setup but hands you control, privacy, and no per-task bill.
Built for AI agents
n8n was rebuilt around AI. Alongside the usual steps, it has an AI Agent node: drop in a model, give it tools, and it can reason and act inside your workflow — not just shuffle data from A to B. That agent-first design is why it shows up so often in AI projects.
n8n isn't just plumbing between apps — it's a place to run agents that think and act on your behalf.
Open-source and self-hostable doesn't mean you must run a server. n8n also offers a hosted cloud plan — you trade some control for zero setup. Same tool, your choice of home (that's the next lesson).
The shape of it
- —n8n is open-source and free — you can read, run, and change it.
- —Self-host it to keep your workflows and data on your own machine.
- —It's agent-first: an AI Agent node can reason and act inside a workflow.
A friend asks why you picked n8n over a rented, pay-per-task automation service. What's the core difference?
