🚀 n8n in a Nutshell: Your Private Workflow Automation Platform

Imagine having your very own Zapier-style automation platform—but totally under your control. No weird data-sharing, no per-action fees, and no cloud lock-in. That’s exactly what n8n gives you.

And the best part? You can run it on-premises and it’s free (with some conditions, but we’ll get into that).

🏗️ What is n8n?

n8n is an open-source, low-code automation tool that lets you create workflows to connect different apps and services. Instead of manually moving data around, you can automate it.

Think of it like a supercharged Rube Goldberg machine for your digital life.

It’s built with Node.js, has a slick UI, and supports hundreds of integrations.

🔧 Self-Hosting: Your Private Automation Platform

Unlike tools like Zapier or Make (Integromat), n8n lets you self-host everything. This means:

• 🛡️ Full Data Control – No third-party storing your automation data.
• 🏢 Run It On-Prem – Install it on your server, Docker, or even a Raspberry Pi.
• 💰 No Per-Task Fees – Unlike Zapier, n8n doesn’t charge per action.
• 🔄 Unlimited Workflows – Automate as much as you want.

Want your own private automation empire? n8n is the tool for the job.

🏗️ n8n = Low-Code Automation

n8n is a low-code platform, meaning you can build powerful automations without writing tons of code.

• Drag and drop nodes to create workflows.
• Use built-in logic like loops, if-else conditions, and variables.
• But if you do want to code, you can write JavaScript snippets inside workflows.

So whether you’re a non-technical user or a dev who loves to tweak, n8n works for you.

🔒 The Single-User Restriction (And How to Work Around It)

Now, before you go installing n8n across your entire company, there’s one thing you need to know.

🚫 The Catch: n8n’s Fair Code License

The Community Edition (CE) of n8n is free to use, but it has a single-user restriction in production. Here’s what that means:

✅ Allowed:

• You can use n8n for free if only one person is managing workflows.
• Multiple users can trigger workflows, but they can’t log in to configure them.
• You can deploy it on your private network for internal automation.

🚫 Not Allowed:

• Multiple people collaborating in the n8n UI.
• Offering n8n as a service to customers.
• Running it in a multi-user production environment without a paid Enterprise license.

🔧 How to Stay Compliant?

If you just need one admin to manage automations, you’re good to go!

But if multiple users need to create workflows, you have options:

• Use API triggers so users interact with workflows indirectly.
• Set up multiple n8n instances (one per user).
• Get the Enterprise Edition (if you need full team collaboration).
