Bottom lineFrom its public pages, Flagsmith offers unlimited flags on every plan, an open-source core and SOC 2 Type II. Team size sets the price, and a few plan details differ between its pricing page and docs.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.
