What Is n8n? A Plain-English Guide for Automation Beginners
If you keep hearing about n8n and want to understand what it actually is, you are in the right place. This page explains n8n in simple terms, shows what you can build with it, and points you to 5,000+ n8n workflow automation templates so you never start from a blank canvas.
Note: This site (n8nresources.dev) is an independent template library. The official n8n product is at n8n.io.
n8n in one sentence
n8n is a free, open-source workflow automation platform with a visual drag-and-drop builder. Think of it as an alternative to Zapier or Make, but one you can self-host, extend with custom code, and use without per-task pricing. It connects your apps, APIs, and databases so they work together automatically -- no manual copy-paste between tools.
How n8n works
Everything in n8n happens on a visual canvas. You build workflows by placing nodes, connecting them with edges, and letting data flow from left to right. Here are the key concepts:
Nodes
The building blocks
Each node represents an app or action -- a Gmail node reads email, a Slack node posts a message, an OpenAI node generates text. n8n ships with 400+ built-in nodes covering popular services and protocols.
Connections (edges)
The data flow
You draw lines between nodes to define the order of operations. Data output from one node becomes the input of the next. Branch, merge, loop, or filter the data at any point.
Triggers
What starts a workflow
A trigger node fires the workflow. Common triggers include a cron schedule (every hour, every Monday), an incoming webhook, a new row in a spreadsheet, or a new message in a chat app. The trigger fires, data flows through your nodes, and the workflow produces an output -- all without you lifting a finger.
What can you build with n8n?
Almost any automation you can describe in steps. Here are six real-world examples:
Slack alerts from form submissions
A Google Form response triggers a workflow that formats the data, checks for duplicates, and posts a summary to a Slack channel within seconds.
AI-powered email triage
Incoming emails are classified by an AI node (OpenAI, Anthropic, or local LLM), then routed to the right folder, label, or team member automatically.
CRM sync between tools
When a deal closes in HubSpot, n8n updates your billing system, creates a project in Notion, and notifies the onboarding team -- all in one workflow.
Automated reporting
Pull data from Google Analytics, a database, and a spreadsheet on a schedule. Merge, format, and email a PDF report every Monday morning.
Webhook-driven pipelines
Receive a webhook from GitHub on every push, run tests via an API call, then post the result back to the pull request as a status check.
AI agent workflows
Build autonomous agents that use tools, call APIs, maintain memory, and make decisions -- all orchestrated visually in the n8n canvas.

n8n vs other automation tools
n8n vs Zapier
Zapier is a polished, fully hosted platform with per-task pricing. n8n is open-source, self-hostable, and does not charge per execution. Zapier is simpler for non-technical users; n8n gives developers more control with code nodes, sub-workflows, and direct API access.

Make also offers a visual builder with operation-based pricing. n8n is comparable in complexity but wins on self-hosting, code extensibility, and having no per-operation fees. Make has a slight edge in its scenario-visualization UI for certain branching patterns.
n8n vs custom code
You could write a Python script or Node.js service to do the same thing. But n8n gives you a visual overview, built-in error handling, credential management, and a library of pre-built connectors -- saving hours of boilerplate. When you do need code, drop a Code node into the workflow and write JavaScript or Python inline.
Getting started with n8n
There are two main paths to start using n8n. Both get you to the same visual editor.
Self-host
Free, full control
Run n8n on your own server with Docker, npm, or a one-click cloud marketplace image. You own the data, control the version, and pay nothing for executions. Ideal if you have some technical experience or want to keep everything on-premise.
n8n Cloud
Managed, no server needed
Sign up at n8n.io for a hosted instance. No Docker, no server management. Great for teams that want to get building immediately without DevOps overhead.
Either way, you do not have to start from scratch. Browse 5,000+ n8n workflow automation templates here on n8nresources.dev, find a workflow that matches your use case, copy the JSON, and paste it into your n8n instance. You can also connect AI assistants to n8n via MCP bridges.
Skip the blank canvas
Instead of building every workflow from zero, start with a tested template. Browse 5,000+ n8n workflow automation templates, filter by app or use case, and copy the JSON directly into your n8n instance.
Frequently asked questions
- Is n8n free?
- The core n8n engine is open-source under a "fair-code" license. You can self-host it at no cost. n8n also offers a paid Cloud plan if you prefer not to manage infrastructure. See n8n.io for official pricing.
- Do I need to know how to code?
- No. Most workflows are built entirely by dragging nodes and drawing connections. However, n8n does support JavaScript and Python inside "Code" nodes for advanced users who want fine-grained control.
- What is the difference between n8n and n8n Resources?
- n8n (at n8n.io) is the official open-source automation platform. n8n Resources (this site, n8nresources.dev) is an independent, curated library of workflow templates built for n8n. We are not affiliated with the n8n company.
- Can n8n handle AI workflows?
- Yes. n8n has built-in nodes for OpenAI, Anthropic, Google Gemini, Ollama, and other AI providers. You can build everything from simple prompt chains to multi-step AI agents with tool use and memory.
