FeatBit

Feature flags for AI release control

About FeatBit

FeatBit is an open-source feature flag platform that helps teams release software with less risk. Flags can target users by attributes, segments, or percentage rollouts, run Bayesian A/B tests, and connect observability signals to release health so a bad rollout can be restored to its last healthy state. Engineering teams can self-host the free Foundation edition or choose commercial and cloud options for advanced governance.
