Why License Compliance Matters

Every open source dependency your project uses carries a license that imposes legal obligations. Copyleft licenses like GPL require you to release your own source code under the same terms — which may conflict with a commercial or proprietary product. License Clearance scans your dependency manifests, classifies every package's license, and flags conflicts against your chosen compliance policy.

With support for npm, PyPI, Go Modules, Cargo, and Maven, this tool works across your entire stack. Optional PDF reports give legal or compliance teams a clear, shareable snapshot of your project's license posture.
