Evaluate feature flags

Feature flags are evaluated for the current person. Use them for staged rollouts, experiments, and remote configuration.

Evaluate flags

Pass the keys you need; pass an empty list to evaluate every flag:

val flags = voidhash.getFeatureFlags(listOf("new_onboarding", "pricing_test"))

val newOnboarding = flags.firstOrNull { it.key == "new_onboarding" }?.enabled == true
val pricing = flags.firstOrNull { it.key == "pricing_test" }

Validate a variant payload before using it; payloads are untyped JSON.

Identity behavior

Flag results are scoped to the current person. The SDK clears them after identify() or a reset so one customer never sees another customer's assignment.

Choose a safe default while flags are loading or unavailable. For paid access, use entitlement grants rather than a feature flag.
