n8n is rapidly becoming the automation platform of choice for businesses that want power, flexibility, and control without the sky-high pricing of enterprise tools. It's open-source, can be self-hosted for free, and supports everything from simple two-step automations to complex AI agent pipelines. Here's everything you need to know.
What is n8n?
n8n (pronounced 'nodemation') is an open-source workflow automation tool with a visual, node-based interface. Each node in an n8n workflow represents an app, service, or action — you connect them together to create multi-step automations. What separates n8n from competitors is the ability to run custom code inside any node, call any HTTP API, and self-host the entire platform on your own server.
Why Businesses Choose n8n
- Cost: Self-hosted n8n is completely free with no limits on workflows or executions
- Power: Execute custom JavaScript or Python code inside any workflow
- Privacy: Your data never leaves your server when self-hosted
- AI integration: Built-in support for OpenAI, Claude, Gemini, and local LLMs
- API flexibility: Call any REST API with the HTTP node — no dedicated integration needed
- Active community: 400+ built-in integrations and growing
Key n8n Use Cases
Business Process Automation
Connect your CRM, email platform, project management tool, and Slack into automated workflows. New client signed? n8n creates their records across all systems, sends a welcome email, creates their Slack channel, and notifies the account manager — in seconds.
AI Agent Pipelines
n8n has first-class support for building AI agent workflows. You can create multi-agent systems where different AI models handle different tasks — one agent researches, another writes, another reviews — all orchestrated by n8n. This is where n8n truly shines over competitors.
Data ETL Pipelines
Extract data from multiple sources, transform it with custom code, and load it into your data warehouse or analytics platform. n8n handles this reliably with built-in error handling and retry logic.
API Orchestration
When you need to coordinate multiple API calls — fetching data from one service, transforming it, and sending it to another — n8n's HTTP node and code nodes make this straightforward, even for complex multi-step API workflows.
n8n's AI agent capabilities are genuinely ahead of Make.com and Zapier. If you're building AI-powered automation — lead scoring, content generation, support automation — n8n should be your first choice.
n8n Self-Hosting vs Cloud
Self-hosting n8n on a $10/month DigitalOcean or Hetzner VPS gives you a fully functional n8n instance with no execution limits. This is ideal for businesses with high automation volumes. n8n Cloud (managed hosting) starts at $20/month and is suitable for businesses that don't want to manage a server.
