Licensee: Open Source License Detection and Compliance Tool

Identify open source licenses, detect incompatibilities and get compliance advice for your software projects with Licensee, an open source license detection and compliance tool.

What is Licensee?

Licensee is an open source command-line tool and Ruby gem created by GitHub that detects licenses of dependencies in software projects. It scans package manifests and file contents to identify licenses and license metadata of dependencies. Licensee matches this information against a curated list of known licenses to provide details on the dependencies' licensing.

Some key features of Licensee include:

  • Detecting a project's declared license in standard locations like LICENSE files
  • Scanning dependency manifests like Gemfile.lock, requirements.txt, and package.json to extract declared licenses of dependencies
  • Scanning file contents looking for license headers and text similarities to known licenses
  • Comparing licenses between transitive dependencies to flag incompatible licenses
  • Providing tailored license notices and advice for improving compliance
  • Available as a command-line tool and Ruby API for easy integration

Licensee aims to improve open source license compliance by giving developers more insight into their projects' dependencies and licenses. The tool helps to surface license incompatibilities and compliance issues early so they can be addressed.
