Flagsmith lets you manage feature flags and remote config across web, mobile and server side applications. Deliver true Continuous Integration. Get builds out faster. Control who has access to new features. We're 100% Open Source. Host with us or on your own infrastructure. Flagsmith combines the concepts of feature toggles with the flexibility of remote config. Rather than just switching features on and off, you can configure them for individual segments, users and development environments. Utilise our powerful rules engine to manage your features for the users you wish to target. You can even use segments for staged rollouts or a/b testing.
