• 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.

• EU hosting and GDPR posture simplify European procurement.
• Good balance between marketer-friendly editing and server-side flags.
• Strong support reputation in European markets.

• 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.

• Less well known outside Europe, with a smaller partner ecosystem.
• Quote-based pricing with no self-serve entry.
• Statistics engine is less differentiated than the warehouse-native platforms.
