n8n (pronounced “N-eight-N”) is an open-source workflow automation platform. It lets you visually connect different apps and services so they can work together without manual effort. Imagine all your favorite tools – email, CRM, spreadsheets, databases – talking to each other automatically.
n8n uses a drag-and-drop interface of nodes on a canvas: each node is an action or a trigger that passes data to the next step. In this way you can build sequences of tasks that run automatically.
N8n UI (Source: n8n)
The platform was founded in 2019 by Jan Oberhauser.
The name “n8n” itself is a clever shorthand: Jan initially coined “nodemation” (node + automation) and then shortened it to n8n (the “8” stands for the eight letters between the two “n”s).
In other words, “n8n” means node automation. It is often read aloud as “en-eight-en.” Because n8n is open-source, anyone can use or modify it, and you can choose to self-host it on your own server or use the n8n Cloud service for a hosted experience.
How n8n Works
At its core, n8n lets you design workflows by connecting building blocks called nodes.
You might start a workflow with a Trigger node (an event like “a new email arrives” or “every day at 9 AM”) and then chain together Action nodes (tasks like “send an email,” “create a database record,” or “post a Slack message”).
Each node on the canvas can be configured with details (for example, which email account or Slack channel to use). When you activate the workflow, the trigger kicks off the chain of nodes and passes data along to each step.
- Nodes and Workflows: n8n uses a visual editor. You drag nodes onto the canvas and connect them. A workflow is simply a series of nodes linked in order.
- Triggers: The workflow starts with a trigger node (for example, a scheduled time, a webhook call, or another app event). Think of it as the “starting gun” for the automation.
- Actions and Data: After the trigger, each node is an action that does something with the data. For example, one node might extract fields from an email and then the next node might post that info to a chat app. n8n automatically handles passing and transforming data between nodes.
- Code When Needed: Most tasks can be handled by built-in nodes, but n8n also has a Code node. In that node, you can write JavaScript (or Python) if you need custom logic. This makes it more flexible than pure no-code tools.
With this setup, you can automate very complex processes (multi-step, conditional logic, loops) without hand-coding each step.
The visual, drag-and-drop approach makes it faster to design and debug flows compared to writing code. You can also see exactly how data moves through each step in the editor.
Key Features
- Hundreds of Integrations: n8n comes with 400+ pre-built integrations (nodes) for popular services – from Google Sheets and Airtable to Slack, GitHub, Salesforce, and many more. This means you can connect almost any app in your workflow without writing a custom integration.
- Open-Source & Self-Hosting: The software is open-source and free to use. You can run n8n on your own server or cloud account. This avoids vendor lock-in and gives you full control over your automation and data.
- Hosted Cloud Service: If self-hosting is too much setup, n8n offers a managed cloud service. You can sign up on n8n.io for a free account and start automating without any installation.
- AI-Native: n8n has built-in support for AI and Large Language Models. You can integrate GPT-style AI models into your workflows, or build multi-step “AI Agent” flows where the AI decides what to do next.
- Workflow Templates: There are many starter templates (over 900) contributed by the community. You can import a template (like “Copy new emails to Google Sheets”) and adapt it instead of starting from scratch.
- Extensible & Custom: Because it’s based on Node.js, you can extend n8n by installing npm packages or writing custom nodes. Advanced users can do virtually anything by combining the visual builder with code.
- Team & Enterprise: n8n supports multiple users and versioning (especially in its cloud or enterprise editions), so teams can collaborate on automations. The enterprise version adds advanced permissions, SSO (single sign-on), and other features for security.
AI-Powered Automations
One of the newest strengths of n8n is its AI integration.
You can drag special nodes into your workflow that call language models or even orchestrate multi-step AI “agents.” This means the automation can “think” and make decisions. For example, you could design a workflow where a user submits a company name.
An AI Agent node in n8n would take that input, call an external API (like a business-info database), and then invoke a language model to clean and organize the results. The LLM effectively decides how to interpret the data, while the rest of the workflow executes those actions. This way, n8n blends AI reasoning with your normal automation steps.
You can also integrate this node with an open source model via Ollama. We have found that this provides a much cheaper alternative to calling paid-for LLMs like ChatGPT, Claude and others with an API.
What’s more, using an open source LLM hosted locally that can work with tools completely removes the need to call third-party models in most cases. We usually prefer this setup when helping clients because it offers the right balance between functionality, privacy, and cost.
How To Install n8n Locally
To use n8n, you first need to install or launch it. The quickest way (for developers) is to use Node.js: simply run npx n8n in your terminal.
This command downloads and starts n8n immediately. Another common method is Docker: n8n provides an official Docker image.
For example, running docker run –name n8n -p 5678:5678 n8nio/n8n will start the n8n server. You can then open your browser to http://localhost:5678 and start building workflows (the n8n docs have full instructions).
If it is your first time starting up n8n via Docker, you may be asked to create an account. Go ahead and create one if you haven’t already, it’s completely free to do! After doing so, you will receive a free license key that you can use to unlock additional features with your local instance.
If you don’t want to install anything, the fastest route is the n8n Cloud. Go to n8n.io and sign up for a free account. The free tier gives you a fully hosted n8n instance. You can start building workflows right away on the web, without handling any servers. As your needs grow, you can upgrade to a paid plan for more capacity, or move to a self-hosted setup for full control.
n8n vs Other Automation Tools
There are several tools in this space – Zapier, Make (Integromat), Microsoft Power Automate, IFTTT, and others – and each has its strengths.
n8n’s unique angle is that it is open-source and self-hostable. With n8n, you’re not locked into a vendor or a pricing plan.
For example, Zapier is a popular SaaS solution, but it requires monthly fees and has usage limits. In contrast, n8n’s core platform can run for free on your own hardware. You won’t hit a hard task limit – you’re limited only by your server’s capacity. n8n also allows more customization (you can insert custom code at any step), whereas some competitors have fixed logic.
In summary, n8n combines a visual workflow builder with the power of custom code and AI integration. It’s especially appealing to developers and technical teams, but its intuitive interface makes it accessible for beginners, too. With a growing community and extensive documentation, you can start automating day-to-day tasks (or even complex multi-step processes) more quickly than writing everything by hand.
