LaunchDarkly vs Statsig vs GrowthBook

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

Free tier available

From $20 per user/month (indicative, cloud Pro)

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.

Dramatically cheaper than the commercial platforms, especially self-hosted at high traffic.

14-day trial; no permanent free tier.

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

Self-hosted open-source edition is free and unlimited; cloud free tier for up to a few users.

• 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.

• Warehouse-native by design — no duplicate event pipeline and no data leaving your control.
• Self-hosting removes per-user-volume pricing entirely.
• Both Bayesian and frequentist engines with sequential testing support.

• 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.

• Requires a working data warehouse and someone who can define metrics in SQL.
• Self-hosting is operational work you own.
• Less polished governance and approval tooling than LaunchDarkly.

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

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

Data-mature teams that already have a warehouse and want to avoid volume-based pricing.
