Facebook Contributor License Agreement

The Facebook Contributor License Agreement: What You Need to Know

If you`re a software developer, contributor, or user of Facebook`s open-source projects, then you`ve probably heard of the Facebook Contributor License Agreement (CLA). But what exactly is it, and what are its implications?

In simplest terms, the CLA is a legal agreement between Facebook and its contributors. By submitting code to Facebook, contributors agree to grant Facebook a license to use, reproduce, modify, display, and distribute their contributions. The license is broad and doesn`t limit Facebook`s use of the code in any way.

Why Does Facebook Need a CLA?

Facebook is a massive company with a large number of open-source projects. A CLA helps Facebook ensure that it has the necessary legal rights to use and distribute code submitted by its contributors. It also helps protect Facebook (and its users) from any legal issues that may arise from the use of open-source code.

Additionally, the CLA helps Facebook maintain the quality and consistency of its codebase. By requiring contributors to sign the CLA, Facebook can ensure that all code submissions meet its standards and comply with its policies.

What Are the Implications for Contributors?

If you`re thinking of contributing to Facebook`s open-source projects, it`s important to understand the implications of signing the CLA. Here are some things to keep in mind:

1. You`re Giving Facebook a Broad License

By signing the CLA, you`re giving Facebook a broad license to use, reproduce, modify, display, and distribute your contributions. This means that Facebook can use your code in any way it wants, without any restrictions.

2. You`re Retaining Ownership of Your Contributions

While you`re giving Facebook a license to use your contributions, you`re not giving up ownership of them. You still own the copyright to your contributions, and you`re free to use them in other projects.

3. You`re Agreeing to Certain Warranties

In the CLA, you`re agreeing to certain warranties, such as the fact that you have the legal right to grant Facebook the license to use your contributions. You`re also agreeing to indemnify Facebook if any legal issues arise from your contributions.

4. Your Contributions May Be Publicly Available

When you contribute code to Facebook, your contributions will be publicly available. This means that anyone can view, download, and use your code.


The Facebook Contributor License Agreement is an important legal document that helps Facebook protect its open-source projects and maintain the quality of its codebase. As a contributor, it`s important to understand the implications of signing the CLA and to ensure that you`re comfortable with the broad license you`re granting Facebook.
