Step 1

Start Unleash

Choose the path that makes the most sense for your team. Run Unleash through our SAAS, hybrid, or private cloud offering, or go local using your pro​​vider of choice.

Step 2

Connect to your favorite SDK

Import your preferred SDK into your project. Quickly set up your SDK using our world-class documentation.

Step 3

Make a feature toggle

Build your code and strategize the environments you want your feature to live in. Then just turn it on.

Step 4


Gradual rollout, canary deployment, A/B testing, or simple deployments: Deploy features with full control of who interacts with your new features, when.


What’s your favorite SDK? There’s a good chance we’re compatible.

Through an official SDKS or through one of our community builds, develop your code in the context that fits you best. Or you could just build your own. We’re flexible.
