n8n is an open-source workflow automation platform (like Zapier but self-hostable). It connects apps, APIs, and AI models in visual workflows. Popular for AI automation: trigger on events, process with LLMs, store results, and take actions.

How does n8n compare to Zapier for AI workflows?

n8n advantages: self-hostable (data stays private), free for self-hosted, more flexible for complex logic, native AI nodes. Zapier advantages: easier setup, more pre-built integrations, better for non-technical users. n8n is the power-user choice for AI automation.

Can n8n integrate with LLMs?

Yes. n8n has native nodes for OpenAI, Anthropic, and local LLMs. You can build AI agents, RAG pipelines, content generation workflows, and data processing chains. The AI agent node supports tool use and multi-step reasoning.

Self-hosted n8n is free and open source (fair-code license). n8n Cloud offers managed hosting starting at $20/month with free tier for basic use. Self-hosting requires Docker or Node.js and gives full control over your data.

How do I self-host n8n?

Easiest: docker run -p 5678:5678 n8nio/n8n. For production: use Docker Compose with a database (Postgres recommended). n8n needs minimal resources—it runs on a $5/month VPS. Add SSL and authentication for security.

What can I automate with n8n and AI?

Popular AI workflows: email classification and auto-response, content generation pipelines, data extraction from documents, customer support automation, social media management, and custom AI assistants with tool access.

Does n8n support RAG and vector databases?

Yes. n8n has nodes for Pinecone, Supabase vectors, and other vector stores. Combined with document loaders and embedding nodes, you can build full RAG pipelines visually. The AI memory features enable stateful conversations.
