Dify is an open-source platform for building and operating applications powered by large language models. Its visual interface combines AI workflows, prompt development, retrieval-augmented generation, agents, model management, and observability, allowing teams to move from an early prototype to a deployable application without building every infrastructure component from scratch.

Dify supports many proprietary and open-source model providers, includes a prompt IDE, RAG pipelines for common document formats, agent tools, APIs, and LLMOps capabilities for monitoring and improving production systems. It can be used through Dify Cloud or self-hosted with Docker, making it suitable for developers and organizations that want a flexible platform for chatbots, internal assistants, knowledge applications, and other model-driven workflows.
