What Is n8n?

n8n is an open-source workflow automation platform. Unlike Zapier or Make, it can be self-hosted, supports code inside workflows, and has no per-task pricing. Here's what it is and what makes it different.

n8n is an open-source workflow automation platform. You connect apps and services visually on a canvas, define what should trigger a workflow and what actions should follow, and n8n runs it — on a schedule, in response to an event, or triggered by another system.

What makes it different from tools like Zapier or Make is that you can run it on your own server, write code inside workflows, and pay a flat infrastructure cost instead of per-task fees.

How n8n Works

n8n uses a node-based canvas. Each node represents a step: a trigger (something that starts the workflow), an action (something that happens in an app), a transformation (reshaping or filtering data), or a code block (custom JavaScript or Python).

You build workflows by connecting nodes together. When the trigger fires — a new row in a spreadsheet, a form submission, a webhook, a scheduled time — n8n executes the nodes in sequence, passing data from one to the next.

A simple example: a new lead submits your contact form → n8n receives the webhook → adds a row to Google Sheets → sends a Slack notification → creates a HubSpot contact. Five nodes. Runs every time, automatically, with no human in the loop.

The Difference Between n8n and Zapier

| | n8n (self-hosted) | Zapier | |---|---|---| | Hosting | Your server | Zapier's cloud | | Price model | Server cost only (~$5–15/mo) | Per task/operation | | Code support | JavaScript + Python | None | | AI integrations | Native (OpenAI, Claude, etc.) | Basic | | Complexity ceiling | High | Medium | | Setup effort | Moderate (technical) | Low |

The business case for n8n becomes obvious once you model the cost difference at volume. 10,000 automated tasks per month on Zapier's Professional plan costs over $49/month — and that plan only includes 2,000 tasks. At 10,000 tasks you are on a higher tier. On self-hosted n8n, the same 10,000 tasks costs the same $8/month server.

What n8n Is Good At

AI-powered workflows. n8n's native AI nodes let you call LLMs, process their responses, branch on the output, and chain multiple AI calls together. This makes it the tool of choice for building AI agent workflows — where a model needs to make a decision and then take action.

Complex multi-step automations. Loops, parallel branches, error paths, conditional logic, sub-workflows — n8n handles all of this on its canvas. Zapier's linear model breaks down when you need real branching logic.

Data transformation. Between any two nodes, you can transform data with a code block. No need to work around what the UI can express — just write the logic.

Self-hosted data control. For businesses that cannot send customer data to a third-party cloud, self-hosted n8n keeps everything on your infrastructure.

What n8n Is Not Good At

No-code beginners. n8n is not Zapier. The canvas model is more powerful but requires more learning. Someone with no technical background will struggle without guidance.

Rare integrations. n8n has 400+ integrations. Zapier has 6,000+. If your business depends on a niche SaaS tool with a Zapier integration but no n8n integration, you will need to use the HTTP node or a workaround.

Immediate setup with zero effort. Self-hosted n8n requires server setup. Even n8n.cloud, the managed version, has a longer onboarding than Zapier's sign-up-and-go experience.

How Businesses Typically Use n8n

The most common business use cases:

  • Lead management. New form submission → enrich with data → score → route to CRM → notify the sales team
  • Customer onboarding. New customer created → trigger email sequence → create accounts in tools → assign to team
  • AI document processing. Invoice received → LLM extracts fields → validate → update accounting system → notify approver
  • Reporting automation. Pull data from multiple sources daily → aggregate → push to dashboard → send summary email
  • Support ticket routing. New ticket → LLM classifies intent → route to right queue → acknowledge customer

Most of these workflows would cost hundreds of dollars per month on Zapier at real business volume. On self-hosted n8n, they run for the cost of a VPS.

Common questions

What is n8n?

n8n (pronounced 'n-eight-n') is an open-source workflow automation platform that lets you connect apps and services, automate tasks, and build AI-powered workflows using a visual canvas. It can be self-hosted on your own server or used via n8n.cloud. It supports over 400 native integrations and allows JavaScript and Python code inside workflows for complex logic.

Is n8n free?

The self-hosted version of n8n is free to use under a fair-code licence. You pay only for the server you run it on — typically $5–15/month for a basic VPS. The managed n8n.cloud has a free tier and paid plans starting at around $20/month. There is no per-task or per-workflow pricing at the self-hosted tier.

How does n8n compare to Zapier?

Zapier is easier to start with but has per-task pricing that scales steeply and limited code support. n8n has a steeper learning curve but a higher complexity ceiling, self-hosting option, no per-task pricing, and native support for AI and code-based logic. Most automation specialists migrate from Zapier to n8n once their workflow volume or complexity grows.

Can n8n run AI agents?

Yes. n8n has native nodes for major AI providers including OpenAI, Anthropic (Claude), and Google. It supports LangChain-style chaining, AI memory, tool-calling, and custom code — making it a strong platform for building AI agent workflows. This is one of the main reasons specialists prefer it over Zapier for AI-powered automation.

What does n8n stand for?

n8n stands for 'nodemation' — the 8 represents the eight letters between the first 'n' and the last 'n'. It is pronounced 'n-eight-n'.
