n8n
Open-source workflow automation with AI nodes. Self-host and build powerful automations without code.
What is n8n?
The AI-Native Workflow Automation Platform
n8n is an open-source workflow automation platform that has evolved into one of the most powerful tools for building AI-powered automations. With native AI nodes for OpenAI, Anthropic, Hugging Face, and other providers, you can build intelligent workflows that process data, draft content, classify inputs, and make decisions — all without writing code.
Why n8n Stands Out
Unlike SaaS automation tools that lock your data in their cloud, n8n can be entirely self-hosted, giving you complete control and unlimited executions on your own infrastructure. Its visual node editor and 400+ integrations make it possible to connect virtually any service to your AI workflows.
- 400+ integrations including all major AI providers
- Self-hostable for unlimited runs and full data control
- LangChain-powered AI agents available as drag-and-drop nodes
- Code nodes (Python/JavaScript) for custom logic
Key Features
Connect AI models to Slack, Gmail, Notion, databases, CRMs, and hundreds of other services natively.
Drag-and-drop LangChain agent nodes let you build autonomous AI workflows that use tools and memory.
Deploy on your own server with Docker for unlimited workflow executions and complete data ownership.
Escape the visual editor when necessary with embedded Python and JavaScript code nodes.
Trigger workflows on schedules, webhooks, database changes, email events, or any external signal.
Who Uses n8n?
Automatically classify, summarize, and route incoming emails using LLM-powered analysis nodes.
Build pipelines that research topics, generate drafts with AI, and publish across multiple platforms.
Monitor data sources and use AI to determine whether an alert is worth sending to your team.
Connect CRMs, databases, and AI to automate complex business workflows that previously required human judgment.
