PostHog

Toggle features for cohorts or individuals to test the impact before rolling out to everyone.

PostHog gives you real-time control over what users see, no redeploys needed. Roll out features gradually, run A/B tests, and kill switch anything instantly. Perfect for teams shipping multiple times a day.

Control releases with percentage rollouts, target specific users or cohorts, and validate changes with built-in experiments. Test in production safely with granular targeting and instant rollbacks.
