n8n is an open-source workflow automation tool — similar to Zapier or Make, but with a key difference: you can run it on your own server, and it’s free to self-host. It’s designed for technical operators and developers who need more control than consumer automation tools provide.

What it is

n8n (pronounced “n-eight-n”) is a visual workflow builder that connects apps and services through a node-based editor. Each node in a workflow represents an action — pull data from a webhook, transform it with JavaScript, send it to Slack. It has over 400 built-in integrations and lets you write custom code within a workflow when needed. You can run n8n on your own server (free) or use n8n Cloud (paid, hosted by n8n). The AI features include nodes for calling OpenAI, Anthropic, and other LLMs, plus an “AI Agent” node for building autonomous agents into your workflows.

What it’s best at

• Automations that need custom logic or code — things Zapier can’t handle cleanly
• Workflows involving multiple data transformations in sequence
• Self-hosted automations where data privacy or cost at scale is a concern
• AI-powered automations: classify incoming emails, summarize support tickets, route leads with LLM logic
• Internal tools that respond to webhooks from other systems
• Scraping, processing, and storing data in a structured pipeline

How operators use it

Operators with some technical background use n8n as the backbone for business automations that would be expensive or impossible in Zapier. Common setups: a webhook receives a new order, n8n calls an LLM to extract and categorize items, then writes the result to a database and sends a Slack alert. Another pattern: a nightly workflow pulls all customer emails, runs them through an AI node to identify complaints, and creates tasks in a project management tool. The self-hosting option is meaningful for operators handling sensitive data who don’t want it passing through a SaaS vendor’s servers.

Getting started & pricing

• Self-hosted (free): Run on your own server or a VPS; full features, no workflow limits
• n8n Cloud Starter ($20/month): 2,500 workflow executions/month, hosted by n8n
• n8n Cloud Pro ($50/month): 10,000 executions, custom variables, more active workflows
• Enterprise: Self-hosted with support contracts; contact n8n for pricing

Start at n8n.io. For a quick test without server setup, sign up for the cloud trial. For self-hosting, n8n has a one-click install on Railway, Render, and similar platforms — usually under 10 minutes.

Bottom line

n8n is the right tool for operators who’ve outgrown Zapier’s simplicity or need to run automations at a cost that doesn’t scale with volume. The self-hosting option is genuinely compelling for privacy-sensitive use cases. The learning curve is real — it expects you to be comfortable with JSON and basic logic — but the payoff is flexibility that no consumer automation tool matches. If you’re not technical, start with Zapier or Make; if you are, n8n is worth the investment.
