Code Mapper: Mapping the Global Contributions of OSS

Free and Open Source Software (FOSS) has reshaped the software landscape. Software developers from around the world contribute to the development and maintenance of these projects. The geographic diversity within FOSS offers insights into community dynamics, collaboration patterns, and inclusivity. Despite the rich insights that can be gained from this geographic diversity, there remains a scarcity of research in this area. One possible reason for this gap in studies is the lack of tools that can identify and visualize the geographic distribution of contributions in OSS projects. We present Code Mapper, a tool that identifies the location of contributors in GitHub projects. To enable users to explore the global influence of their projects, Code Mapper visually presents the geographic distribution of project contributors. To accelerate future research in this area, we have deployed Code Mapper at https://codemapper.alwaysdata.net and have made our source code publicly available online. A demonstration of Code Mapper can be viewed at https://www.youtube.com/watch?v=AtARvrBJbVM.
