ConfigCat vs Statsig

From $110 per month (Pro)

Free tier available

Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.

One of the most generous free tiers in developer tooling; paid usage is billed on analytics events, not seats.

Free forever plan with a monthly config-request allowance and unlimited members.

Generous free tier including unlimited feature flags and a large monthly event allowance.

• Unlimited team members at every tier, so product and support can toggle flags too.
• Very simple to adopt — an afternoon, not a project.
• Broad SDK coverage including Dart and Elixir.

• Statistics engine is genuinely strong — sequential testing and CUPED are not marketing veneer.
• Flags, experiments and analytics in one system removes a whole class of integration work.
• Warehouse-native mode satisfies data-governance requirements.

• No experimentation or analytics to speak of.
• Limited targeting sophistication compared to LaunchDarkly.
• Small vendor.

• Event-based pricing can escalate sharply on high-volume products.
• Broad surface area means a real learning curve.
• Changed hands twice in under a year — OpenAI acqui-hired the founding team in September 2025, and Amplitude took over the product and brand in May 2026, so the roadmap is still settling.

Teams that want simple, cheap flags accessible to the whole company.

Product teams that want experimentation and analytics to share one source of truth.
