What n8n is, and what it actually automates.

A tool that connects the apps you already pay for and does the work between them without anyone sitting there doing it by hand.

Short version: n8n is an open-source automation platform. You wire up a process — "when this arrives, do that" — and it runs itself. You can host it on your own server for a few euro a month, which means your data never leaves your infrastructure and you are not paying per task.

How it works in practice

Every workflow has three parts. A trigger — what starts it: a new email, a submitted form, a time of day, a payment. Steps — what happens next: reading data, checking a condition, reshaping it, asking a model something. An action — where the result lands: a row in a sheet, a Slack message, a CRM record, a reply.

You connect those into a diagram and switch it on. After that it runs whether or not anyone is at work.

One real example

An enquiry arrives by email. Until now somebody opened it, retyped the name, the phone number and what they wanted into a spreadsheet, tagged the email, and messaged the colleague who handles it. Four minutes, fifteen times a day.

Automated: n8n reads the email, an AI step pulls out the name, number and request, adds the row, tags the message and posts a summary to Slack with a link. Four minutes becomes zero.

Fifteen enquiries at four minutes is an hour a day. Twenty-two working days is twenty-two hours a month. That arithmetic is what makes automation an easy decision — not the technology.

All three change their pricing; check their own pages before comparing numbers.

There is no universally right answer. If you need two simple workflows and do not want a server, Make will do the job and I will say so. n8n wins once the workflows multiply, once they touch personal data, or once you would rather the cost not grow with every request handled.

What it costs

  • ·A server — €5 to €10 a month is enough for a small business running a few workflows
  • ·Building a workflow — from €69 with me for one process connecting two tools
  • ·AI steps — charged on use, typically a few euro a month at this volume
  • ·Maintenance — optional, and worth it once a workflow becomes load-bearing

If one process is eating an hour a day, it pays for itself inside a month at any of those numbers.

What is not worth automating

Automation earns its place on work that is frequent, predictable and rule-bound. The reverse is also true, and more useful to say out loud:

  • ·Something you do twice a month — the build time will not come back
  • ·Decisions that need judgement where a wrong call is expensive
  • ·A process still in flux — settle it first, then automate it
  • ·A conversation where the customer expects a person. An automatic reply in a place that expects a human costs more than it saves

Frequently asked questions

Is n8n free?
The software is open source and you can self-host it, in which case you pay only for the server — usually €5 to €10 a month for a small business. n8n also sell a cloud version if you would rather not run a server. The licence allows internal use freely; the restrictions only apply to reselling n8n itself as your own product.
n8n or Make?
Make is easier to start with and needs no server. n8n is more flexible, drops into code where a workflow needs it, and can be entirely yours. Few simple workflows: Make. Many workflows, sensitive data, or you would rather not pay per task: n8n.
Do I need to be able to code?
To use a finished workflow, no. To build one it helps but is not required — most steps are configured through the interface. The boundary shows up fast: the moment data needs reshaping in a non-standard way, or a service has no ready-made node, it becomes development work.
Where does my data go?
Self-hosted, it never leaves your server except to the services you deliberately put in the workflow. That is the main reason companies handling customer data pick n8n over the cloud-only alternatives.
