Abstract The static structures of developer collaboration networks in OSS communities have been widely discussed in the literature. However, there has been limited research on the evolutionary process of these networks. In this paper, we construct the developer collaboration network of the Cloud Foundry community by code-collaboration relationships and analyze its structure and evolution. The results show that the collaboration network evolution is characterized by the structural variations of its giant component, namely “loosely connected” state, “chain-module” structure, and multi-modular small-world network with a “core-periphery” structure. Meanwhile, the evolution of the giant component is intrinsically related to the sub-projects. Besides, the collaborative relationship between developers shows the combined features of preferential-attachment, homophily, and heterophily. The overall results may be not only helpful to deepen our understandings of the collaborative pattern in OSS communities, but also enrich the studies of open innovation in the large-scale crowd.
