Modulescan

Modulescan is a software analysis tool designed to examine modular codebases to identify module boundaries, dependencies, licensing, and potential security risks. It is commonly used in organizations that manage large, multi-project systems built from reusable components.

Its core capabilities include building dependency graphs, parsing manifest files across languages, detecting version conflicts and duplicate dependencies, and flagging unused modules. It also performs license checks against SPDX data and can correlate known security advisories with installed modules. Outputs typically include JSON reports, HTML summaries, and SARIF for security tooling.

In practice, modulescan is run against a repository or registry, locally or in CI. Policies such as allowed licenses, minimum versions, and ignored modules are configured to tailor results. The tool can generate a bill of materials and a per-module risk score for developers, security teams, and compliance staff.

Technical architecture commonly includes a scanner engine, manifest parsers (for package.json, go.mod, pom.xml, requirements.txt), a dependency-resolution component, a policy engine, and a report generator. Optional integrations may provide registry lookups, SBOM generation, and connections to issue trackers.

Limitations include dependence on up-to-date manifests and registries, possible false positives, and performance considerations for large repositories. Privacy and access controls are important when scanning private codebases.

The term modulescan is used across toolchains to describe module- and dependency-scanning. There is no single universally adopted standard, and implementations vary in scope and language support.
