Reduce risk and recover faster from failure

Say goodbye to messy rollbacks and hotfixes. Instead, use feature flags to roll out to a small percentage of users to reduce risk and fail safer. If you detect errors, performance spikes, or user backlash, just switch off the feature toggle to roll back - all without redeploying code. Rollouts make your release process more resilient.

Better continuous delivery with Rollouts

Stop dealing with painful merge conflicts. Move away from long-lived feature branches and start adopting feature flags for greater development velocity, safer code deployments, and increased developer productivity.

  • Feature flags

    Separate code deploy from feature release. Easily turn features on or off with feature toggles.

  • Experimentation

    Run A/B tests on your feature flags to quantify the impact of new features and optimize existing features. Run 1 concurrent experiment at a time.


    Integrate rollouts with your development workflow to manage feature flags at scale.

  • Change history

    Keep track of all of the updates to your features with a detailed log. Easily troubleshoot issues by filtering by the type of activity.

  • Remote configuration with cloud dashboard

    Remotely configure your flags and experiments in our UI. Powerful feature variables, enable you to parameterize your app and update features on the fly.

  • Support for multiple environments

    Manage rollouts and experiments across development, staging, production and custom environments.

  • Staged rollouts

    Test and learn by rolling out first to a small set of users, then ramping up over time.
