Kameleoon
Kameleoon SAS · France · since 2008
French enterprise experimentation and personalization platform, web testing, feature management and AI personalization on one engine, aimed at regulated sectors (healthcare, finance, ecommerce) that care about data residency and compliance.
Best for Teams that want three statistical methods available without an upgrade
The verdict
Kameleoon puts frequentist, Bayesian and sequential analysis side by side in the entry tier, adds CUPED, multiple-testing correction and sample-ratio-mismatch detection, and exports to BigQuery, Snowflake and Segment. Two things cost it on a measurement lens. Its headline reliability figure is one minus the p-value, which is not the probability that the variation wins, and it will be read as if it were. And the Statistics at Kameleoon methodology document returned a 404 at every URL we tried on 1 September 2026, which is the wrong direction for a vendor whose statistics are otherwise a selling point.

Strengths
- Genuine consent-mode engineering: four documented modes, and Delayed Mode renders experiments while writing nothing to the device until consent arrives, few competitors document this depth.
- Real EU option with European infrastructure: OVHcloud and Hetzner instead of a US hyperscaler, substantive for buyers whose objection is US jurisdiction.
- Statistical breadth in the box at the entry tier: frequentist + Bayesian + sequential, CUPED, multiple-testing correction and SRM detection on the $495 plan.
- Broad, independently attested compliance: ISO 27001:2022 with published SoA, SOC 2 Type 2, PCI DSS, HIPAA BAAs.
- One engine for web, flags and personalization with synchronized frontend/backend visitor identifiers.
Weaknesses
- The Shopify app has zero reviews after four-plus years, a merchant gets no peer signal at all, and checkout testing needs Plus plus custom development.
- The important features are Enterprise-gated: feature management, personalization, mobile testing and the dedicated code editor are all excluded from the $495 Starter.
- Visual-editor friction on modern front-ends is a recurring review theme (SPAs, CSS issues, flicker, broken Chrome extension), cutting against the "no dev needed" positioning.
- Steep learning curve and enterprise-shaped cost; AI Predictive Targeting needs 7 days AND 100,000 visits before producing anything, excluding lower-traffic sites.
- Documentation hygiene gaps: expired TLS certificate on the developer docs host, 404ing methodology PDF, and vendor pages that disagree on integration count.
The facts
| Statistics | Frequentist, Bayesian AND sequential testing side by side, plus CUPED, multiple-testing correction and SRM detection, all included at the entry tier. Caution: the reported "reliability" metric is 1 − p-value, not the probability the variation wins. |
| Shopify | Shopify app carries the "Built for Shopify" badge but has 0 reviews after 4+ years (listed June 2021). Checkout testing needs Shopify Plus plus a developer-built Checkout UI extension and cart-attribute plumbing, not point-and-click. |
| Privacy & hosting | European infrastructure without US hyperscalers: subprocessors are OVHcloud (France) and Hetzner (Germany); EU and North America data regions exist (EU residency is a choice, not automatic). Four documented consent modes, Delayed Mode renders experiments while writing and transmitting nothing until consent. ISO 27001:2022, SOC 2 Type 2, PCI DSS. |
| Pricing | PBX Starter from $495/month (10 experiments, 50,000 tracked users), the only enterprise-class tool here with a public entry price. Enterprise is custom. 30-day free trial (3 experiments, no credit card). Feature management, personalization and the dedicated code editor are Enterprise-only. |
