The goal of the AboutCode community is to promote the use of free and open source (FOSS) software by making it easier for anyone to understand and reasonably comply with the conditions of FOSS licenses. Our work is not about legal interpretation of license text or promotion of any particular license and we do not offer any legal advice. Our work is about helping people and organizations to:

  • Discover and identify FOSS components and packages already in your code
  • Document the origin and license of the FOSS components and packages you use
  • Comply with FOSS license conditions based on how you use FOSS components and packages

AboutCode was founded by nexB in 2014. Our projects now include contributions from many other people, projects and organizations including students from the Google Summer of Code and Google Season of Docs programs. We are currently participating the Google Summer of Code program for 2022 with four projects.


Contributions are welcome and appreciated for any of our projects! Every bit helps – bug reports, code, documentation, design ideas and use cases are just examples.

Our primary programming language is Python, our primary application platform is Django and our primary documentation platform is ReadtheDocs. We apply the principles of Test-driven Development to all of our work.

The primary licenses for AboutCode projects are Apache 2.0 for code and CC BY 4.0 for documentation.

When you contribute to an AboutCode project you must agree to the Developer Certificate of Origin. This is used by the Linux Kernel developers and many other FOSS projects.

In the interest of fostering an open and welcoming environment, we as participants, contributors and maintainers pledge to make participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation.

Our code of conduct is adapted from the Contributor Covenant Version 1.4.
