What is n8n?

n8n (pronounced “n-eight-n”) is an open-source, no-code/low-code workflow automation platform designed to help users connect apps, services, and APIs to automate complex tasks visually. Unlike many cloud-only automation tools such as Zapier or Make.com, n8n allows self-hosting, giving you full control over your workflows and data.

Its modular architecture is built around “nodes,” each representing a trigger, action, or service. You visually connect these nodes to create workflows that can span multiple applications, APIs, and data sources. The platform is built to be highly extensible, supporting custom code when needed.

Why Choose n8n Over Other Automation Tools?

Many automation platforms charge based on the number of workflow executions or limit features on lower-tier plans, making scaling costly and restrictive. n8n’s open-source nature and self-hosting capabilities eliminate these barriers.

Key Advantages:

• No Limits on Workflows or Executions: Run as many workflows as your server supports.

• Data Privacy & Security: Keep your data on your infrastructure without sharing it with third parties.

• Customization & Extensibility: Add custom JavaScript, build custom nodes, and modify workflows to fit your unique needs.

• Cost Savings: Avoid subscription fees by hosting n8n on affordable cloud servers or VPS providers.

• Active Community: Benefit from a growing ecosystem of integrations, templates, and support.
