n8n is a node-based workflow automation platform that combines a visual no-code editor with the flexibility to add custom code, enabling technical teams to automate business processes and integrate systems. It offers native AI capabilities, a large ecosystem of 400+ integrations, and a fair-code / source-available approach so teams can self-host or use managed cloud offerings while retaining control over data and deployment. Developers can extend n8n with custom nodes, use webhooks and APIs for triggers, and deploy workflows for scheduled or event-driven automation across SaaS, databases, and internal systems. Its value lies in blending rapid visual automation building with deep extensibility, data ownership, and enterprise features like managed cloud and support plans.
