n8n is an open-source, self-hostable workflow automation platform with 400+ integrations and a native AI-agent node built on LangChain primitives.
Why teams pick it
- Fair-code licensed — self-host for free, or use n8n Cloud.
- Visual + code — drag-and-drop nodes plus inline JavaScript/Python.
- AI agent node — LLM, tools, memory, and vector stores as first-class nodes.
- Data privacy — everything runs in your infrastructure if you self-host.
When to reach for it
- Internal automations where data cannot leave your VPC.
- Complex branching workflows that go beyond Zapier's linear model.
- Teams who want to version-control their automations (n8n stores workflows as JSON).
