Introduction: Why Everyone Is Searching "What Is n8n"
Every day, people copy data between apps, send the same emails, update spreadsheets and share reports by hand. n8n AI (pronounced "n-eight-n") is a tool that does all of this for you automatically. And in 2026 it has become even more popular because of n8n AI features that let you build smart AI agents without heavy coding.
In this guide, I (Subodh Barsagade) explain what is n8n, how n8n workflows work, how n8n automation saves time, how n8n AI works and what n8n pricing looks like, in simple words with diagrams and examples.

What Is n8n?
n8n is a low-code workflow automation tool. You build a flow on a visual canvas by joining small blocks called nodes. Each node does one job: read an email, call an API, ask an AI model a question, save a row in Google Sheets, send a Slack message.
The name comes from "nodemation" (node + automation). n8n was created by Jan Oberhauser in Berlin and uses a fair-code license, n8n AI which means the source code is open to view and you can self-host it, but some commercial use is restricted.
Why do people choose n8n?
- Visual builder: see your whole automation as a flow chart.
- Self-hosting option: run it on your own server and keep your data private.
- Developer friendly: add JavaScript or Python code when drag-and-drop is not enough.
- Hundreds of integrations: Gmail, Slack, Notion, Google Sheets, WhatsApp, databases, HTTP APIs and more.
- Built-in AI nodes: connect LLMs, memory, tools and vector databases.
How n8n Workflows Work
An n8n workflow always starts with a trigger (something that begins the flow) and then runs one node after another. Here is a typical example:
Example n8n workflow: a trigger starts the flow, an AI node processes the data, and the results go to Google Sheets and Slack.
Key Building Blocks of n8n Automation
| Term | Simple meaning | Example |
|---|---|---|
| Workflow | The complete automation from start to end | Lead capture to CRM |
| Trigger node | The event that starts the workflow | Webhook, schedule, new email |
| Action node | A step that does something | Send Slack message |
| Credentials | Saved logins and API keys | Google account, OpenAI key |
| Execution | One full run of a workflow | Counted for n8n pricing |
| Code node | Run your own JavaScript or Python | Clean or reshape data |
Real n8n Automation Examples
- Lead management: new website form → add to Google Sheets → send welcome email → alert sales team on Slack.
- Content workflow: every morning fetch news → AI writes a summary → post to your blog or LinkedIn draft.
- Customer support: new support email → AI classifies urgency → create a ticket → reply with a suggested answer.
- Invoices: email with PDF invoice → extract data → save in accounting sheet.
- Developer tasks: GitHub issue opened → notify the channel → add to a project board.
n8n AI: Build AI Agents and LLM Workflows
n8n AI means using AI models inside your workflows. n8n includes AI nodes where you can connect an LLM (such as Claude, GPT or Gemini), add memory, give the model tools to use (search, calculator, your own APIs) and even connect a vector database for RAG (Retrieval-Augmented Generation).
What can you build with n8n AI?
- A chatbot that answers from your own documents (RAG).
- An email assistant that reads, sorts and drafts replies.
- A research agent that searches the web and writes a report.
- A data-entry agent that reads PDFs and fills your spreadsheet.
Tip: always add a human approval step before an AI sends emails or changes important data.
n8n Pricing in 2026
n8n pricing is execution-based. One execution means one full run of a workflow, no matter how many steps it has. A 20-step workflow counts the same as a 2-step one, which is a big reason n8n can be n8n AI cheaper than step-based tools. n8n prices its cloud plans in euros, so your local currency cost can change with the exchange rate.
| Plan | Approx. price | Best for |
|---|---|---|
| Community Edition (self-hosted) | Free (you pay only for your server) | Developers, learners, privacy-focused users |
| Cloud Starter | About €20/month (billed annually), 2,500 executions | Individuals and small projects |
| Cloud Pro | About €50/month (billed annually), more executions | Small teams, higher volume |
| Business | Several hundred euros per month (reported figures vary) | Companies needing self-hosted business features |
| Enterprise | Custom quote | SSO, audit logs, SLA, large scale |
Important: prices and limits change often (for example, n8n removed active-workflow limits in April 2026, so plans now differ mainly by executions). Always confirm the latest numbers on the official n8n pricing page before you buy. A 14-day free trial is usually available on Cloud plans.
Self-hosted or Cloud: which is cheaper?
- Self-hosted: software is free and you can run unlimited executions, but you manage the server, backups, updates and security. A small VPS is often enough to start.
- Cloud: costs more per month but needs zero server work, which is better for non-technical users.
n8n vs Zapier vs Make
| Feature | n8n | Zapier | Make |
|---|---|---|---|
| Ease of use | Medium | Very easy | Easy to medium |
| Self-hosting | Yes | No | No |
| Custom code | Strong (JS and Python) | Limited | Moderate |
| Pricing style | Per workflow execution | Per task (step) | Per operation |
| Best for | Developers, AI workflows, complex logic | Beginners, quick setups | Visual builders |
Pros and Cons of n8n
Pros:
- Flexible and powerful for complex n8n workflows.
- Free self-hosted option with full data control.
- Strong n8n AI features for agents and RAG.
- Whole-run execution counting can lower cost for long workflows.
Cons:
- Steeper learning curve than Zapier for complete beginners.
- Self-hosting needs basic server and security knowledge.
- Cloud plans have execution limits that high-volume users can hit quickly.
How to Start with n8n in 5 Steps
- Choose a setup: start a free Cloud trial, or run n8n locally with Docker or Node.js.
- Create a new workflow and add a trigger (for example, Schedule or Webhook).
- Add action nodes such as Google Sheets, Gmail or Slack and connect your credentials.
- Test the workflow using "Execute workflow" and check each node's output.
- Activate it so it runs automatically, and watch the Executions tab for errors.
Pro tips from Subodh Barsagade
- Start with one simple automation, not a giant workflow.
- Add an Error Trigger workflow so you get an alert when something fails.
- Never hard-code API keys. Use n8n credentials.
- Back up your workflows (export as JSON) and use clear node names.
Conclusion
So, what is n8n? It is a flexible workflow automation platform that lets you connect apps, run n8n automation on autopilot and build smart n8n AI agents, all from a visual canvas. With a free self-hosted version and affordable cloud n8n pricing, it is a great choice for developers, startups and anyone who wants more control than basic automation tools offer.
My advice: build one small workflow today, like "new form entry to Google Sheets to Slack alert", and then add an AI step. You will understand n8n faster by doing than by reading. Questions? Ask in the comments and I will reply.
