About

What is Dify?

Dify is a rapidly growing open-source LLM application development platform that enables teams to build AI-powered workflows, chatbots, and agents through a visual orchestration canvas. It supports RAG pipelines with a built-in knowledge base, agent tool calls, multi-model routing, prompt engineering, and API publishing — all without requiring deep LangChain or LlamaIndex knowledge. With 50+ LLM integrations and an active community, Dify has become the most complete open-source platform for AI application development.
