Overview

Dify is an open-source LLM application and agent development platform built by the China-based team LangGenius, and it has long been among the top-starred projects of its kind on GitHub. It bundles model calls, RAG knowledge bases, workflow orchestration, agent strategies, and observability into one visual interface, and ships official Docker images, so a small team can run the full platform on a single server. The business model is open core plus a cloud subscription, with the cloud edition hosted overseas. Dify sits between no-code platforms like Coze and pure code frameworks: more controllable and self-hostable than the former, more out-of-the-box than the latter. It fits enterprise technical teams with data-sovereignty requirements that want to own their prompt and workflow engineering. On data residency: self-hosted deployments keep all data local; the official cloud stores data outside mainland China.
