What it is

License-Checker is a tool that helps developers verify the licensing status of their project's dependencies, ensuring compliance with open-source license requirements and avoiding potential legal issues.

License-Checker stands out as a simple, yet effective tool specifically designed to help developers manage and verify the licenses of their project's dependencies without requiring extensive setup or configuration.

When it fits — and when it doesn’t

A good fit for

  • JavaScript developers who need to ensure their project's dependencies comply with open-source license requirements.

  • Teams that require automated compliance checks as part of their CI/CD processes.

  • Projects with complex dependency trees where manual tracking is impractical.

Look elsewhere if

  • Developers working in languages or ecosystems not supported by the tool.

  • Users who need real-time updates on license changes for dependencies.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited support for non-NPM ecosystems

    Primary focus on Node.js projects, limited functionality with other package managers like Maven or Gradle.

  2. 02

    Inadequate handling of transitive dependencies

    May miss licenses from deeply nested dependencies which can lead to incomplete reports.

  3. 03

    Manual configuration for complex projects

    Requires detailed setup and configuration, especially in large-scale or monorepo environments.

  4. 04

    Outdated license data

    License information is only as current as the package metadata; outdated packages may provide incorrect licensing details.

What it does well

  • Checks licenses of all dependencies in a project.

  • Generates reports on license compliance.

  • Supports various package managers and ecosystems.
