About n8n
n8n is a workflow automation platform that combines traditional app-to-app integrations with built-in AI Agent and LLM nodes, all built on a visual, node-based canvas. It connects to hundreds of apps and services, supports conditional logic and error handling for complex flows, and can be self-hosted for free under its fair-code license, or used as a managed cloud service. It's a strong self-hosted alternative to tools like Zapier for teams that want AI woven directly into their automation.
