Roll out features safely. Toggle features for cohorts or individuals to test the impact before rolling out to everyone.
Deliver features safely
Deploy updates behind a feature flag to test it with increasing numbers of users, then rollback easily if there’s an issue.
Multivariate testing
Breakdown our analytics by feature flag variant to understand the impact on performance.
Target on users’ properties, or their behavior
Test changes based on criteria like plan, geography or LTV, or users’ previous behavior.
Feature flags tutorials
