# n8n

> An open-source workflow-automation tool that connects apps, APIs and AI models into repeatable pipelines — self-hostable, so data can stay on your own infrastructure.

A workflow in n8n is a graph of nodes: a trigger (a webhook, a schedule, a new email) starts it, and each node transforms or routes the data — calling an API, running code, asking a language model, writing a row. It occupies the space between Zapier-style no-code tools and writing the integration from scratch: visual enough to inspect, code-capable where the job needs it.

The property that decides most real deployments is where it runs. Self-hosted on the client's own server, customer data never leaves the client's infrastructure — which is why n8n shows up so often in projects where the data being automated is the sensitive part. Credentials, retries and error alerting live inside the workflow rather than in an employee's memory.
