 It-Depends is a tool to automatically build a dependency graph and Software Bill of Materials (SBOM) for packages and arbitrary source code repositories. You can use it to enumerate all third party dependencies for a software package, map those dependencies to known security vulnerabilities, as well as compare the similarity between two packages based on their dependencies.
