What Is n8n? Workflow Automation Explained Simply

n8n is a workflow automation tool that connects apps and runs tasks automatically, like Zapier or Make, but you can host it yourself for free. You build workflows by linking nodes on a visual canvas: a trigger (a new form, an email, a schedule) followed by actions (create a CRM contact, post to Slack, call an AI model). n8n Cloud starts at €20 a month for 2,500 workflow executions on annual billing, and the self-hosted Community edition is free.

How n8n works

Every n8n automation is a workflow made of nodes:

1. A trigger node starts the workflow: a webhook, a schedule, a new row in a spreadsheet, a new email.
2. Action nodes do the work: read or write data in apps, transform data, call an API, run code or ask an AI model.
3. Logic nodes decide what happens: filters, if/else branches, loops, merges.

When the trigger fires, the workflow runs from left to right. Each complete run is one execution, which is what n8n Cloud bills.

A simple example

A new lead fills in a form on your website. n8n:

1. Receives the form data through a webhook.
2. Checks whether the email already exists in your CRM.
3. Creates or updates the contact.
4. Asks an AI model to summarize the lead's message.
5. Posts the summary to your sales channel in Slack.
6. Sends the lead a confirmation email.

On n8n that is one execution per form submission. On Zapier, each of the 5 actions would count as a task.

What can you automate with n8n?

• Sales: route new leads, enrich contacts, create follow-up tasks.
• Marketing: sync signups to your email tool, publish content to several channels, collect form responses.
• Operations: generate invoices, move files between storage services, back up data.
• AI workflows: summarize emails, classify support tickets, draft replies, build AI agents that call tools.
• Internal tools: scheduled reports, alerts when a metric changes, data clean-up jobs.

n8n Cloud vs self-hosted

A small VPS is enough to start self-hosting; pricing guides put a basic VPS at about $5 to $20 a month. Read our step-by-step guide on how to self-host n8n and the full n8n pricing breakdown.

n8n vs Zapier vs Make

* From 2026 pricing guides.

Choose n8n if your workflows are long, run often, use code or AI, or must stay on your own servers. Choose Zapier if you want the easiest setup and the most app integrations. Choose Make if you want a visual builder with a generous free plan. See n8n vs Zapier and n8n alternatives.

Why n8n has become popular

• Price at volume. Counting runs instead of steps makes complex workflows affordable.
• Self-hosting. Companies can keep data on their own infrastructure.
• AI. n8n's AI and code nodes make it a common choice for building AI agents and automations.
• Flexibility. When there is no ready-made integration, you can call any API or write code.

Limitations to know

• Learning curve. n8n is more technical than Zapier; non-developers may need time.
• Maintenance when self-hosting. Updates, backups and security are your responsibility.
• Cloud execution limits. Starter's 2,500 executions can run out if workflows poll often.
• Fewer ready-made integrations than Zapier. You may need HTTP requests for niche apps.

How to get started with n8n

1. Start a Cloud trial to learn the editor without installing anything.
2. Rebuild one real workflow you do by hand today, such as saving form leads to your CRM.
3. Measure executions for two weeks to see which plan you need.
4. Decide on hosting: stay on Cloud for simplicity, or self-host if you have a server and the skills.
5. Add error handling: an error workflow that alerts you when something fails.

n8n terms explained

• Workflow: an automation made of connected nodes.
• Node: one step: a trigger, an app action, logic, code or AI.
• Trigger: the event that starts a workflow.
• Execution: one complete run of a workflow.
• Credentials: the stored logins and API keys n8n uses to access your apps.
• Community edition: the free, self-hosted version.

Who should use n8n?

• Developers and technical founders who want full control and low cost.
• Agencies building automations and AI workflows for clients.
• Companies with data rules that need automations on their own servers.
• Teams outgrowing Zapier's per-task pricing.

Who should not: non-technical teams that need a few simple automations and the widest app library. Zapier will be faster for them.

Three workflows small businesses build first

1. Lead capture to CRM

Form submission → check for duplicates → create the contact → notify the team. Saves copy-pasting every lead and makes sure nobody is missed.

2. Invoice reminders

Every morning, a schedule trigger reads unpaid invoices from your accounting tool, filters those overdue by 7 days and sends a polite reminder. One execution per day: about 30 a month.

3. Support triage with AI

New support email → an AI node classifies it (billing, bug, question) → the workflow tags it and routes it to the right person, drafting a reply for simple questions. Saves the first minutes of every ticket.

Security basics if you self-host n8n

• Put n8n behind HTTPS with a domain and a reverse proxy.
• Use a strong encryption key and keep it backed up: it protects your stored credentials.
• Restrict who can log in, and keep n8n updated.
• Back up the database and the n8n data folder daily, and test a restore.
• Run n8n in its own container so it cannot affect other apps on the server.

Common mistakes when starting with n8n

• Polling every minute. A schedule that runs every minute uses 43,200 executions a month; use webhooks or longer intervals where you can.
• No error alerts. Without an error workflow, a broken automation can fail silently for days.
• Hard-coding secrets. Store API keys in n8n credentials, not inside nodes.
• One giant workflow. Very large workflows are hard to debug; split by purpose, while keeping related steps together.
• Self-hosting without updates. Old versions miss fixes and security patches; schedule updates monthly.

Our verdict

n8n is the automation tool to learn if you are comfortable with a little technical work. It rewards that effort with low costs at volume, full control over your data and the flexibility to build AI workflows that simpler tools can't handle. Start on n8n Cloud to learn, then decide whether self-hosting is worth it for your team.
