Abstract: A software library recommendation engine provides an analysis and aggregate dashboard comparison of metrics denoting maintainability trends in a plurality of libraries from a publicly available software repository. Maintainability trends include regularity and magnitude of changes (commits), resolution of user inquiries for issues, problems and bugs, and an estimation of core contributors for estimating inertia and longevity of a plurality of candidate libraries under consideration for a particular usage. Usage metrics coalesce and summarize usage data of libraries under consideration for comparison, and a dashboard of computed metrics provides an indication of trends that indicate reliability or longevity to mitigate vulnerability of the library user from dependence on the collaborative intent of the library author and contributors.
