The short version

  • Only Google Optimize has a free tier, so it costs nothing to try first.
  • Each has a real cost: Google Optimize google Optimize and Optimize 360 were sunset and are no longer available as of September 30, 2023; Kameleoon no rate card is published. Reported entry pricing around several hundred euros a month for the limited prompt-based tier comes from third parties rather than Kameleoon, so any budget you build before contacting sales is a guess.
  • They diverge on capability: Google Optimize covers A/B testing, Kameleoon covers Visual A/B test editor.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Optimize

  • Google Optimize and Optimize 360 were sunset and are no longer available as of September 30, 2023
  • Any experiments and personalizations still running on that date were ended by Google
  • Google directs former users to third-party A/B testing tools, naming AB Tasty, Optimizely and VWO, rather than a replacement Google product

Kameleoon

  • No rate card is published. Reported entry pricing around several hundred euros a month for the limited prompt-based tier comes from third parties rather than Kameleoon, so any budget you build before contacting sales is a guess.
  • Web experimentation, feature experimentation and personalisation are licensed as separate capabilities, so the unified platform story costs materially more than the entry configuration most buyers are first quoted.
  • The partner and agency ecosystem is concentrated in France and continental Europe; a buyer in North America or Asia will find fewer implementation specialists and less community knowledge than for Optimizely or VWO.
  • The integration catalogue is smaller than the market leaders, so a stack built on less common analytics or CDP tooling may need custom work that a larger vendor would cover natively.
  • Client-side visual testing still carries the structural problems of the approach, including performance cost and single-page-application fragility; the anti-flicker engine reduces the symptom but does not remove the dependency on the DOM staying stable.

Kameleoon: Does Kameleoon publish pricing?

No. Pricing depends on monthly tested users and which capabilities you licence, and requires a sales conversation.

Kameleoon: Can I keep data in the EU?

Yes. EU hosting and a GDPR-first consent model are among the main reasons European buyers shortlist it.

Kameleoon: Does it do feature flags as well as A/B tests?

Yes, through server-side SDKs, sharing audiences and results with the visual testing side.

Kameleoon: How does it compare with Optimizely?

Similar capability at a smaller scale. Kameleoon's advantages are European data residency and an independent vendor; Optimizely's are ecosystem size and partner availability.
