The Open Source Feature Flagging Service

Unleash marketing image showing "Flexible segmentation", "Feature toggles", "Projects" and that Unleash integrates with many programming languages.

Unleash is the largest and fastest growing open source feature flag project in the world. We exist to fill an essential space in the development stack and decouple code deployment from releasing features. At first, we were a side project, then just a few contributors, and now we are many. Together we have built an amazing product and community.

We love that you — our community — have the freedom to work with our product in any way you want. Together we can test, experiment, and create a well-rounded product that covers a ton of different use cases. We're super proud of all we've done together

That's enough about us. Have fun. Be kind. Let's Unleash great software together.
