Dify

Dify is an open-source LLMOps platform founded by Zhang Luyu in March 2023, built to help enterprises develop and operate AI applications globally . The company positions itself as one of the earlier teams to coin and push the term "LLMOps," betting that the widespread availability of GPT APIs would create new demand for tools handling RAG, agents, and application iteration .

By late 2024, Dify had reached 51,000 GitHub stars and over one million global installations of its open-source version, while serving more than 30 Fortune 500 clients and achieving profitability as an early-stage company . Zhang has described open-source as core to product strategy, noting it accelerates global expansion and builds trust with enterprise customers—particularly in reputation-sensitive markets like Japan—without requiring complex credentialing . The company also received early backing from Yunqi Capital, which led its first round .
