Which Tool Should You Pick?
Pick n8n if…
- You want a visual drag-and-drop builder that non-developers can use to create automated workflows with AI-powered steps — no Python or TypeScript required.
- Self-hosting or data sovereignty is a requirement, and you need an automation platform that runs on your own infrastructure with fair-code licensing.
- You're automating business processes (CRM sync, email routing, data transformation) where AI is a component, not the entire product.
Pick LangChain if…
- You're a developer building custom LLM-powered applications (chatbots, RAG systems, agent workflows) that need fine-grained control over prompts, chains, and tool use.
- You need 700+ integrations with LLM providers, vector stores, and data sources — and the ability to compose them programmatically.
- Production observability is essential — LangSmith provides tracing, evaluation, and debugging for deployed LLM applications.
