IconVault's License Audit finds the license problems hiding in your dependency tree. Paste or upload your package.json, pick your project license, and the tool resolves every dependency's real license from the npm registry, then grades each one as ok, review, conflict or unknown. Strong copyleft licenses like GPL and AGPL are flagged when they clash with a permissive or proprietary project license, and weak copyleft licenses like LGPL and MPL get a review warning.

Resolution happens in your browser against the public npm registry; nothing you paste is stored. It is free with no signup. The honest caveat: this tool is not legal advice. Registry license metadata can be wrong or missing, and real compliance depends on how you use and distribute the code. Treat conflicts as a starting point for review with counsel, not a verdict.
