What Makes n8n Different?

Zapier and Make are cloud-only platforms. You pay per automation. Your data goes through their servers.

n8n gives you choice:

Local – run it free on your computer to test and learn. Perfect for experimentation.

Self-hosted – deploy on your own server. Unlimited automations, no monthly costs, your data stays with you. Pay only for your server.

Cloud – want convenience? Use n8n’s cloud version for quick start without setup.

Your choice. Your control.

AI Workflow Builder: The Game-Changer

n8n just launched AI Workflow Builder – their newest feature that changes everything.

Instead of manually building workflows, you simply describe what you need:

“When I get an email with ‘urgent’ in the subject, send it to Slack and create a task in Notion.”

AI builds the entire workflow for you. All the nodes, connections, data mapping, logic — done in seconds.

The catch? It’s only available in the cloud version.

But here’s the thing — we built our own AI Workflow Builder for self-hosted n8n. And it turned out to be easier than you’d think.

Subscribe to our blog — we’ll publish a detailed guide showing exactly how we did it, what technologies we used, and how you can build your own. Step by step, with code and architecture.

So What Exactly Is n8n?

Let’s look at two examples:

Simple automation: New email arrives → copy to Google Sheets → send Slack notification. Three steps, done.

Complex automation: Here’s where n8n shows its real power.

Build a workflow that automatically spins up a cloud instance via API, deploys your own local LLM on it, processes your sensitive documents through that model, extracts the results, and shuts down the instance, all without human intervention.

The result? Your sensitive data never leaves your infrastructure. Processing costs drop from dollars to pennies per request. And you control everything, end to end.

That’s the power of n8n. From simple copy-paste automations to complex AI-powered systems that handle your most sensitive data securely.

n8n opens up a world where automation isn’t limited by pre-built templates or monthly costs. Whether you need simple task automation or complex multi-step workflows with AI, n8n gives you the tools and control to build it.
