| Bottom line | From its public pages, ConfigCat is the most focused flag service here, with the most team controls on its free plan. Its score reflects no built-in experimentation and a shorter compliance list. | From its public pages, LaunchDarkly is the broadest platform here, with experiments on every plan and a long compliance list. Client-side users drive the bill, and SSO and audit logging are listed for Enterprise. | From its public pages, Statsig gives the most for nothing here: unlimited seats and flag checks, with experiments and analytics on the free plan. SSO and EU hosting need Enterprise, and the product now sits within Amplitude. | From its public pages, Unleash puts enterprise governance on a self-serve plan and never bills for traffic. Its score reflects per-seat pricing with no hosted free plan and no built-in experiment analysis. |
