Statsig vs ConfigCat

Free tier available

From $110 per month (Pro)

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

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.

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

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

• 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.

• 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.

• 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.

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

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

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