Faster experiments Fewer procedures

Test and try out new features confidently. Gradual rollouts allow you to mitigate risks by enabling new features to 1% of users and then expanding.

Feature Management

Some say what we do is impossible. We say: try us.

Feature Management platform built with privacy, simplicity, and flexibility in mind, Unleash lets developers drive the innovation of your business.

  • Wherever you host software: we’re there

    Multi-region hosting means you can decide to host your instances anywhere in the world, giving you unmatched freedom, flexibility, safety, and speed.

  • Everything we do is context-aware

    You don’t need to store or process sensitive private data from your users or their devices. This means you can segment, target, and test at will — all while respecting user privacy.

  • Play it safely with our proxy

    Quicker and more secure, the Unleash proxy connects to your client-side apps in a way that keeps sensitive data where it belongs. No leaks and nothing to slow down your business or your user experience.
