• 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.

• 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.

• 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.

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