Why Use a CLA?
A Contributor License Agreement (CLA) is a legal document that defines the terms under which a contributor grants rights to their contributions — protecting both maintainers and contributors.
Why Projects Use CLAs
Intellectual Property Protection
Without a CLA, copyright of each contribution remains with the individual. A CLA ensures the project has the rights it needs to use and distribute all contributions.
License Flexibility
If a project needs to change its license (e.g. GPLv2 to GPLv3), CLAs mean it can do so without tracking down every past contributor for permission.
Legal Clarity
A CLA provides a clear, documented record that each contributor has agreed to the terms — especially important for regulatory compliance.
Patent Protection
Many CLAs include patent grants, protecting the project and its users from patent claims by contributors.
Who Uses CLAs?
Many major open-source projects and organizations require CLAs, including Apache Software Foundation, Google, Microsoft, Meta, and the Cloud Native Computing Foundation. It's a well-established practice in the open-source ecosystem.
