Dify

Dify is an open-source LLM application development platform that provides a visual workflow builder, RAG pipeline construction, agent configuration, and model management in a single self-hostable tool. It supports all major LLM providers and lets teams build, test, and deploy AI applications with a low-code interface. Startup developers, enterprise AI teams, and solo builders use Dify to build production AI applications without extensive LLM infrastructure code. The visual prompt orchestration, RAG integration, and agent tools reduce development time from weeks to days for common AI application patterns. Dify has become one of the most starred open-source AI application platforms on GitHub (50,000+ stars), reflecting its value for teams building custom AI products. Its deployment options (cloud, on-premise, Docker) serve both teams wanting managed infrastructure and those requiring data sovereignty.
