• Observation and experimentation in one place shortens the hypothesis loop.
• Visual editor is capable and marketer-friendly.
• Cheaper than Optimizely at comparable traffic.

• 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.

• Module-based pricing means the useful configuration costs much more than the headline.
• Client-side flicker on complex single-page applications.
• Server-side capability lags the flag-first platforms.

• The most expensive option in the category by a distance.
• Experimentation is competent but less sophisticated than dedicated statistics platforms.
