Strengths
- 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.
- Unlimited experiments and seats, so nobody rations testing to save licence cost.
- Serious privacy posture with EU hosting and no data resale.
- Transparent, published pricing.
Limitations
- 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.
- Client-side only — no server-side experimentation.
- No feature-flag capability.
- Smaller vendor with a modest ecosystem.
