// EDITOR'S TAKE
GrowthBook is the closest in spirit because it pairs flags with experiment analysis run against your own warehouse data, which is the adoption feedback loop Bucket sells. Unleash is the more mature and battle-tested flag platform if you only need targeting and gradual rollouts, while Flipt suits teams who want flags defined in Git alongside code.
