KAIYUANSHE

KAIYUANSHE (开源社) is China's largest open-source community, described by Yunqi Capital as "中国影响力最大的开源社区" . It functions as a hub for open-source collaboration and knowledge dissemination in China, partnering with venture firms and tech companies to advance the ecosystem.

Yunqi Capital has been a particularly close collaborator since at least 2022. The firm co-published the *China Open Source Annual Report* with KAIYUANSHE for three consecutive years through 2023 , with Yunqi's team authoring the commercialization section each time . In 2022, KAIYUANSHE invited Yunqi as the only market-oriented fund partner for its annual conference, where Yunqi hosted a commercialization sub-forum featuring speakers from VMware, RisingWave, Jina, EMQ, and Second State . The partnership extended to 2025, when Yunqi and the OpenAtom Foundation (开放原子基金会) jointly launched a *China Open Source Deep Development Report* .

KAIYUANSHE's role in the ecosystem, as framed by Yunqi's contributors, resembles what one investor called a "slime mold" model of exploration: a decentralized community where multiple directions are tested simultaneously, with successful paths then strengthening into dominant channels—helping avoid technological "local optima" .
