Dify

Dify is an open-source platform for developing LLM applications, taking projects from prototype to production through a visual interface. A drag-and-drop workflow canvas sits alongside a RAG pipeline that ingests PDFs, PowerPoint files, and other documents, agent capabilities with more than 50 built-in tools such as Google Search, DALL-E, and WolframAlpha, and a prompt IDE for crafting and comparing prompts. It connects to hundreds of models including GPT, Mistral, and Llama series plus any OpenAI-compatible API, and its LLMOps layer monitors production usage for continuous prompt and model improvement. Applications expose APIs out of the box, so teams can embed them into existing products. Self-hosting requires only Docker Compose on a modest machine, community Helm charts cover Kubernetes, and a hosted Dify Cloud is available. The code ships under the Dify Open Source License, an Apache 2.0 variant with extra conditions. Teams that want visual orchestration instead of glue code are the core audience.
