• The most capable visual editor for non-technical experiment authoring.
• Deep personalisation and audience-targeting features.
• Established statistics with sequential testing, so peeking is handled correctly.

• Genuinely good hybrid model — the same experiment can run client- and server-side.
• Effective anti-flicker implementation.
• EU hosting with healthcare-grade compliance options.

• Expensive, with a suite-oriented sales motion that pushes adjacent products.
• Client-side testing causes flicker and is increasingly blocked by browsers and blockers.
• Heavyweight for teams that only need a handful of experiments.

• Smaller market presence outside Europe.
• Only the entry tier is priced publicly; everything above it is a sales conversation.
• Fewer third-party integrations than Optimizely.
