Flagsmith is a fully supported open-source Feature Flag, Remote Configuration, and A/B testing tool. You can use our hosted API to deploy to your private cloud or on-premise. Flagsmith makes it easy for you to create and manage feature flags across web, mobile and server-side applications. Flagsmith allows you to toggle the feature on or off in different environments, users, or user segments by wrapping a section of code with a Flag. Feature flags - Release new features with confidence using phased rollouts. Remote configuration - You can toggle individual features on or off and make changes without having to deploy new code. Segments for A/B Testing and Multivariate Tests - Use segments to perform A/B or multivariate testing on new features. Segments can also be used to introduce beta programs in order to gain early user feedback. Organization Management - Help keep your deployment organized by creating projects and organizations, as well as assigning roles to team members.
