// EDITOR'S TAKE
Unleash is the closest on architecture and SDK coverage, and its edge proxy is the piece most teams need to replace LaunchDarkly's relay. GrowthBook is stronger when experiment analysis matters more than flag plumbing, and Flipt is the lean, Git-driven option if you just want flags running inside your own infrastructure.
