What is n8n?

n8n (pronounced “n-eight-n”) is an open-source workflow automation platform that allows users to connect apps, APIs, and services into automated workflows using a visual editor.

Instead of writing complex scripts, users build workflows by connecting nodes — each representing a trigger, action, or data transformation step.

• Low-code / no-code automation
• Visual workflow builder
• Self-hosted + cloud options
• Supports AI integrations

Think of n8n as a “digital orchestrator” that connects tools like Slack, Google Sheets, APIs, and AI models into a unified workflow.
