Dify lets people who can't write backend code build production-ready AI applications by dragging and dropping nodes, and every workflow it produces comes with its own API endpoint. Its core value isn't "saving time writing code" — it's pulling four things that normally require separate setups (prompt management, RAG retrieval, model switching, and log tracing) into a single interface. What Problem Does Dify Actually Solve Before Dify, building a "customer service bot that can search company documents" required combining at least five components: a vector database, an embedding service, retrieval logic, prompt template management, and conversation history storage. Each one had to be wired together with code, and any change to any part meant redeploying. Dify turns these five things into nodes on a canvas — make your changes, hit "Publish," and it takes effect. Dify is an open-source LLMOps platform developed by the LangGenius team, released under a modified license based on Apache 2.0 (with additional trademark and multi-tenancy restriction clauses). "Over 110,000 GitHub stars and more than 900 contributors (2026)" (Source: langgenius/dify GitHub Repository) , making it one of the largest community projects among comparable open-source AI application platforms. It sits between two extremes. On one end are general-purpose automation tools like n8n and Zapier, where AI is just one node among many, lacking prompt version control and deep RAG integration. On the other end are code frameworks like LangChain and LlamaIndex — extremely flexible, but you have to write Python. Dify fills the middle ground: visual operation, but with API and code nodes preserved as escape hatches. The Differences Between the Four Application Types When creating an application in Dify, you have to pick a type first, and picking the wrong one means rebuilding the entire structure later. Here's when each of the four types applies. Chatbot Suited to conversational scenarios with a single role that
