Dify

Provider: LangGenius

Dify is an open-source platform (also available as managed cloud/SaaS) for building LLM-powered agents and RAG workflows. It offers a visual canvas to design “apps” that combine LLM reasoning, retrieval from knowledge docs, prompts, tool integrations (Zapier via MCP), and deployment—all with built-in logs and observability. It supports OpenAI, Anthropic, Llama2, Hugging Face, and customizable agents.
