LangGenius (Dify)

Company

LangGenius is the company behind Dify, headquartered in Suzhou, China, with a growing international team. It was founded in 2023 by Luyu Zhang and a former team from Tencent Cloud to build an open-source LLM application platform.

Product — Dify

Dify (github.com/langgenius/dify, 130K+ stars) is a self-hostable LLMOps platform combining a visual agent workflow builder, RAG pipeline, multi-provider LLM gateway, and prompt management. It uses the Dify Open Source License — a modified Apache 2.0 with a non-compete clause prohibiting multi-tenant SaaS resale. Internal enterprise use and single-tenant customer deployments are permitted.

Positioning

Dify targets product teams building AI features without assembling a separate tool for each layer (RAG, gateway, agents). Its main competitors are Flowise, LangFlow, and build-it-yourself stacks on top of LangChain / LlamaIndex.

Cloud offering

LangGenius also operates dify.ai as a hosted SaaS with free and paid tiers. The self-hosted version covers the core functionality and runs as a Docker Compose stack with Postgres, Redis, and a vector database.
