The short version

  • Each has a real cost: 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.; Katalon real cost stacks three separate charges, per-seat authoring licence, the True Platform add-on for test management, and per-session cloud execution, so the advertised seat price significantly understates total spend for a team running cloud tests regularly.
  • They diverge on capability: Kameleoon covers Visual A/B test editor, Katalon covers Low-code test recording.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

Katalon

  • Real cost stacks three separate charges, per-seat authoring licence, the True Platform add-on for test management, and per-session cloud execution, so the advertised seat price significantly understates total spend for a team running cloud tests regularly.
  • Since it is built on Selenium and Appium underneath, a team with strong automation engineers can replicate most of the core capability for free, paying only for optional cloud execution elsewhere, making Katalon's value proposition mainly about authoring speed rather than unique capability.
  • The steep first-three-seats discount versus the fourth-seat-and-beyond price means cost per seat rises sharply as a team scales past three testers on Katalon Studio alone.
  • Low-code recorded tests can become brittle and hard to maintain at scale in the same way any record-and-playback approach does, requiring the team to still write real code for complex scenarios.
  • Enterprise pricing is quote-only, so the largest deployments lose the pricing transparency the published seat tiers otherwise offer.

Answered from the vendors’ own pages

Kameleoon: Does Kameleoon publish pricing?

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

Katalon: Is Katalon free?

No, though a 30-day free trial with no credit card is offered; the product is commercial with per-seat licensing.

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.

Katalon: Does Katalon replace Selenium and Appium?

No, it is built on top of them; Katalon adds a low-code authoring layer, test management and cloud execution rather than a different automation engine.

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.

Katalon: Is cloud execution included in the seat price?

No, TestCloud cross-browser and mobile sessions are billed separately, at 197 US dollars a session monthly or 1,899 annually per session.

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.
