n8n: The Free Automation Tool That Replaces $500/Month in SaaS

I was paying $73/month across three automation tools: Zapier ($49), Make ($9), and IFTTT ($15). Each one handled a different set of workflows because none of them could do everything.

Then I found n8n. I replaced all three with one tool. And since I self-host it on a $5/month server, my total automation cost went from $73/month to $5/month.

n8n has 182,000 GitHub stars. It's the most popular open-source automation platform in the world. And in 2026, it's good enough to replace expensive SaaS automation tools for most use cases.

What Is n8n?

n8n (pronounced "n-eight-n") is a workflow automation platformthat connects apps and services visually. You drag and drop "nodes" (triggers and actions) to build workflows — no code required.

It does what Zapier does, but with key differences:

• Self-hostable. Run it on your own server for free. Your data never leaves your infrastructure.
• Fair-code licensed. Source code is public. You can inspect, modify, and contribute to it.
• 400+ integrations. Slack, PostgreSQL, OpenAI, Gmail, Notion, GitHub, Stripe — everything you need.
• Pricing by execution, not task. One workflow that processes 500 items counts as 1 execution, not 500 tasks.

n8n vs. Zapier: The Real Comparison

When to choose Zapier instead:If you need an obscure integration that n8n doesn't have, or if you never want to think about hosting. Zapier's 7,000+ integrations vs. n8n's 400+ is a real gap — but n8n covers the 95% of apps most people actually use.

5 Workflows That Replace Expensive Tools

3. Invoice Processing (Replaces: $50/mo document automation)

The 2026 Killer Feature: AI Workflow Builder

n8n's newest feature is the AI Workflow Builder. Instead of dragging and dropping nodes manually, you describe what you want in plain English:

This collapses the learning curve from "watch 3 YouTube tutorials" to "describe what you need."

The Honest Downsides

• Fewer integrations than Zapier. 400 vs. 7,000+. If you need a niche app connector, check n8n's library first.
• Self-hosting requires maintenance. Updates, backups, SSL certificates. If "manage a server" sounds exhausting, use n8n Cloud.
• Steeper initial learning curve. Zapier is simpler for basic 2-step automations. n8n's power shows up in complex multi-step workflows.
• Community support vs. enterprise support. Self-hosted users rely on forums and docs. Paid plans get direct support.

The Bottom Line

If you're spending $50+/month on automation tools and most of your workflows use common apps (Slack, Gmail, Notion, Stripe, OpenAI), n8n can cut that cost to near zero. The AI Workflow Builder means you don't even need to learn the visual editor — just describe what you want.

Start with npx n8n to test locally. Build one workflow that replaces a manual task you do every week. If it saves you 30 minutes, you have your answer.
