Dify

Dify lets teams build AI workflows, RAG pipelines, agents, and chatbots through a visual interface, without writing the underlying infrastructure code themselves. It supports every major model provider, ships with a built-in vector database, and can be fully self-hosted, which has made it one of the most popular open-source AI app builders — product teams use it to ship AI features fast, while developers hook into its API to embed Dify workflows in existing applications.
