Dify

About

Dify is an open-source LLM application development platform that provides a visual orchestration interface for building production-ready AI applications without writing extensive code. It covers the entire application lifecycle: building AI features with a drag-and-drop workflow editor, managing multiple LLM providers under a unified interface, creating RAG pipelines by connecting knowledge bases and vector stores, configuring AI agents with tools and function calling, and publishing applications as APIs or embedded widgets. One of Dify strongest features is its built-in RAG pipeline that handles document ingestion, chunking, embedding, and retrieval automatically. You upload PDFs or other documents, and Dify processes them into a searchable knowledge base that your AI application can query. The platform supports multiple LLM providers including OpenAI, Anthropic, Llama, and local models, letting you switch between models without changing your application logic. Dify also includes conversation management, prompt engineering tools, annotation and feedback collection, and analytics dashboards for monitoring application performance. For developers building custom AI applications, Dify reduces development time by providing ready-made infrastructure for common patterns like knowledge base Q&A, chatbot, and AI agent workflows. The open-source version can be self-hosted, while the cloud version provides managed hosting starting at USD 59 per month. Compared to Langflow which focuses on visual flow building, Dify offers a more complete application platform with built-in data management and deployment infrastructure.
