Maintaining an open source project that builds on upstream code is challenging. This post discusses how the anywhere-labs deepseek-harness-desktop project handles upstream evolution through submodules, version tracing, and a non-fork architecture. By using submodules, the project can track specific upstream versions while keeping local modifications separate. Version tracing ensures that changes are attributable and reversible. The non-fork approach avoids the maintenance burden of traditional forks, making it easier to merge upstream updates. For open source maintainers, this offers a practical strategy for balancing customization with upstream alignment. The article provides a clear framework for implementing these practices, which can be applied to various projects.
