Variart

Variart is an innovative application designed to support multiple variants of features, enabling users to experience different functionalities or user interfaces within a single application. This capability is particularly useful for feature rollouts, configuration updates, and experimentation, such as A/B testing. By utilizing variant feature flags, developers can assign specific variants to users, groups, or percentile buckets, allowing for targeted testing and feedback collection.

One of the key features of Variart is its ability to manage multiple variants with distinct configurations. Each variant can be defined with a name and an optional configuration value, which can range from simple JSON primitives to complex JSON objects. This flexibility allows developers to differentiate functionalities or user experiences and configure them with variant-specific settings. Additionally, allocation rules can be set to define the target audience for each variant, ensuring that the right users receive the intended experience.

Variart also includes default variants and a kill switch feature. The default variants, such as DefaultWhenEnabled and DefaultWhenDisabled, ensure that users receive a consistent experience even if they are not explicitly assigned to a variant. The kill switch allows developers to quickly disable a feature if issues arise, ensuring that users are redirected to a safe default variant. This feature is crucial for maintaining application stability and user satisfaction during testing or deployment phases.
