What is n8n?
n8n (pronounced "n-eight-n", short for "nodemation") is a workflow automation tool that connects the apps your business already uses so data and tasks move between them automatically — no manual copy-paste, no per-task fees, and you can run it on your own server. This is the plain-English guide for businesses: how it works, what it really costs, and when it's worth getting help.

What n8n is, in one minute
n8n is a source-available workflow automation platform. You build "workflows" that watch for an event (a new email, a form submission, a new order) and then carry out a sequence of steps automatically — reading data, transforming it, calling an AI model, and updating other apps.
Think of it as the wiring between your tools. Most small businesses run on a handful of apps that don't talk to each other — a website, an inbox, a CRM, an accounting package like Xero or MYOB, maybe a booking system. Someone on the team spends hours every week shuttling information between them by hand. n8n does that shuttling for you, reliably, 24/7.
Two things make n8n stand out from the better-known names: it is self-hostable (you can run it on infrastructure you control), and it does not charge per task (so the cost doesn't explode as your volume grows).
How n8n works
An n8n workflow is a chain of "nodes" on a visual canvas. A trigger node starts it; action nodes do the work; the data flows left to right from one node to the next.
The building blocks
- Trigger node — what starts the workflow. A new email arrives, a webhook fires, a row is added to a sheet, or it runs on a schedule (e.g. every morning at 7am).
- Action nodes — the steps. Fetch a record, call an API, run an AI prompt, branch on a condition, loop over a list, send a message.
- Connections — the lines between nodes. Data ("items") flows along them, and each node transforms or adds to it.
- Credentials — stored securely once, reused across workflows, and (when self-hosted) held entirely on your own server.
You build and test it visually, watch real data move through each node, then activate it. From then on it runs without anyone touching a keyboard. n8n has 400+ pre-built integrations, and for anything without a dedicated node you can call any API directly or drop in a few lines of JavaScript or Python.
A real example
Here's a workflow we build often for real-estate teams (the full version is in our real estate automation guide):
- Trigger: a new enquiry lands from realestate.com.au.
- Enrich: n8n looks up the property and recent comparable sales.
- Score: an AI node rates how serious the buyer is, 0–100.
- Route: the lead is added to the CRM and assigned to the right agent.
- Respond: the customer gets an instant SMS, and a viewing is offered.
Six steps, about 11 seconds per lead, and nobody re-typed anything. The same shape — trigger, enrich, decide, act — covers healthcare no-show recovery, Shopify order automation, and invoice processing into Xero.
What n8n costs
n8n itself is free to self-host — you only pay for the server it runs on. n8n Cloud is paid and varies by plan and execution volume. The big saving versus Zapier or Make is that n8n does not bill per task.
| Option | Typical cost | Best for |
|---|---|---|
| Self-hosted (Community) | Server cost only | Full control, data residency, high volume |
| n8n Cloud (Starter) | Paid plan | No server admin, light to moderate volume |
| n8n Cloud (Pro) | Paid plan | Teams, more executions, more active workflows |
| Enterprise | Custom | SSO, audit logs, SLAs, regulated industries |
For a full breakdown including server sizing and hidden costs, see our n8n pricing guide. The headline: at high volume, a workload that can cost hundreds of dollars on Zapier can run for a small infrastructure cost on self-hosted n8n.
Self-hosting & privacy
Because n8n can run on your own server, sensitive data can stay inside infrastructure you control.
Fully managed tools route your data through servers you don't control. With self-hosted n8n you decide where it runs, who can see credentials, and how long logs are kept. For accountants, medical practices, and legal firms handling sensitive client data, that control is often the deciding factor. Our self-hosting n8n guide covers the setup, and the agentic AI for business guide covers governance for AI-driven workflows.
n8n vs Zapier, Make & Power Automate
Zapier is the easiest to start with but charges per task and can't be self-hosted. Make is visual and mid-priced. Power Automate suits Microsoft-heavy shops. n8n wins on cost at scale, self-hosting, and complex logic.
| Tool | Self-host? | Pricing model | Best fit |
|---|---|---|---|
| n8n | Yes | Flat / server cost | Volume, control, data residency |
| Zapier | No | Per task | Very light, non-technical use |
| Make | No | Per operation | Visual mid-volume |
| Power Automate | No | Per user / flow | Microsoft 365 environments |
We've written honest head-to-heads for each: n8n vs Zapier, n8n vs Make, and n8n vs Power Automate.
Who uses n8n
n8n suits any business with repetitive, rules-based work spread across multiple apps. The sweet spot is small and mid-sized businesses past the point where manual processes hurt but below the budget for enterprise software. Common cases:
- Trades & services — never miss a call or quote; book jobs automatically.
- Real estate — capture, score, and route every lead (see real estate automation).
- Healthcare — fill cancellations and recover no-shows (see Cliniko automation).
- E-commerce — sync orders, inventory, and marketing (see Shopify automation).
- Accounting & ops — invoice OCR into Xero / MYOB, approvals, reporting.
- Any team adding AI — n8n is a leading way to put AI agents to work (see AI agent setup).
How to get started with n8n
- Find the bleed. Pick the one manual process costing the most time each week. (Not sure? Try our automation readiness assessment.)
- Map it. Write out every step a person does today — trigger, decisions, apps touched.
- Choose hosting. Self-host for control and cost, or n8n Cloud to skip server admin.
- Build one workflow. Start with a single high-value automation, test it on real data, then activate.
- Harden it. Add error handling, logging, and alerts so it fails safely and you know when it does.
Steps 4 and 5 are where most DIY attempts stall — a workflow that works in a demo but breaks quietly in production is worse than none. That's the gap a specialist n8n consultancy closes. If you'd rather have it built right the first time, a workflow audit is the fastest way to find what to automate first.
Frequently asked questions
What does n8n stand for?
n8n is short for "nodemation" — node + automation — written with the middle eight letters numeronymed to "8", the same way "internationalization" becomes "i18n". It's pronounced "n-eight-n".
Is n8n free?
Yes — the self-hosted Community Edition is free under a fair-code licence; you only pay for the server it runs on. n8n Cloud and Enterprise are paid.
Do I need to be a developer to use n8n?
No. Simple workflows are built visually. Advanced ones can use small code snippets, but most business automations need none. Many teams hire help for the first builds, then maintain them in-house.
Can n8n use AI like ChatGPT or Claude?
Yes. n8n has dedicated nodes for OpenAI, Anthropic Claude, and others, plus AI-agent tooling — so a workflow can read, decide, and write like a human assistant. See AI agent setup.
Is n8n secure?
Self-hosting lets you keep all data and credentials on infrastructure you control, which is why privacy-sensitive teams choose it. Security still depends on configuration — credentials, access control, and logging — which is part of what we harden.
Want n8n set up properly — and owned by you?
