Abstract The loss of key developers in the open-source community will cause changes in the psychology and behavior of remaining developers, leading to a series of cascading effects. Considering the impact of the loss of key developers on the work intensity and collaboration willingness of remaining developers under the following effect, a dynamic cascade failure model with load capacity changes is designed. Taking the open-source design platform AngularJS as an example, the dynamic robustness of the open-source community developer collaboration network is investigated. The results show that the threshold of anti-interference ability of open-source community developer collaboration network has an optimal interval. The robustness of the developer collaboration network is greatly affected by the initial load distribution and is the weakest in the mode of the highest load node loss. The results are beneficial for the management and operation of open-source community.
