Statsig vs LaunchDarkly

Free tier available

From $12 per seat/month plus context-based usage (indicative)

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

Priced on seats plus monthly contexts (roughly, unique users evaluated). High-traffic consumer products get expensive.

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

14-day trial; no permanent free tier.

• 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.

• Extremely reliable flag delivery with offline fallbacks — this is infrastructure you can trust in the request path.
• Best-in-class governance: approval workflows, audit logs, role-based access.
• Code references and stale-flag detection actually help you remove dead flags.

• Event-based pricing can escalate sharply on high-volume products.
• Broad surface area means a real learning curve.
• Now owned by OpenAI, which introduces strategic uncertainty for some buyers.

• The most expensive option in the category by a distance.
• Experimentation is competent but less sophisticated than dedicated statistics platforms.
• No meaningful free tier for evaluation.

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

Engineering organisations where flags are critical infrastructure and governance is required.
