Unlike closed SaaS automation platforms (like Zapier or Make), n8n offers self-hosting, full customization, and enterprise-grade security, making it ideal for developers, IT teams, and businesses that need scalable, privacy-focused automation.

This comprehensive guide covers:
✔ What n8n is and how it works
✔ Key benefits over competitors
✔ Real-world use cases
✔ Step-by-step setup guide
✔ Advanced features for power users

By the end, you’ll know whether n8n is the right automation tool for your needs.

What is n8n? #

n8n is an open-source workflow automation platform that enables users to connect different applications, APIs, and services using a visual, node-based editor. It was founded in 2019 by Jan Oberhauser and has since grown into one of the most popular self-hosted automation tools, with 70,000+ GitHub stars and a thriving community.

Key Features #

✅ Self-Hosted or Cloud-Based – Run n8n on your own servers or use n8n.cloud.

How Does n8n Work? #

n8n uses a node-based system where each node represents an action (e.g., fetching data, transforming it, or sending it to another app). Workflows are built by connecting these nodes in a sequence.
