What is n8n? The 30,000-foot overview before you build
If you keep seeing n8n everywhere and want the plain-English version of what it actually is, start here. No setup required, this one is the big picture.
n8n is a visual agent-orchestration platform. You build a workflow node by node and you can actually see what is happening, instead of handing everything to a black-box agent. It is no-code / low-code, it self-hosts, and it has built-in integrations for just about every app and AI model out there. I started my automation journey on it three years ago, and most of my workflows still run on it today.
The reason it is worth learning comes down to two things: control and cost.
- Control: you are not locked to one vendor. You can run the same job through Claude, OpenAI, or a local model and keep whichever does it best.
- Cost: the only part that costs money is the AI node itself. The code, the databases, and the API calls are free, instead of paying a cloud agent to burn expensive output tokens on every request.
In the video I walk through three real workflows I run (an email assistant that drafts replies, a product-photo generator, and a LinkedIn job scraper), then build a simple one from scratch so you can see how little it takes to get started.
How to start:
- n8n cloud is about $20/month and a fine place to begin.
- But if you have a reasonably modern computer, especially an Apple Silicon Mac, self-host it free on Docker. That is what I recommend.
- Want a head start? Grab the free starter kit (local n8n in Docker)
This is the foundation. The hands-on builds (the Google setup, the email assistant, and more) branch off from here.
Watch the overview above, then tell us in the comments: what is the first thing you want to automate?
