LaunchDarkly vs Statsig

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

Free tier available

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

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

14-day trial; no permanent free tier.

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

• 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.

• 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.

• 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.

• 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.

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

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