Kameleoon: cost, fit and limits
Kameleoon is an experimentation and personalization platform from the French company Kameleoon that lets marketing and product teams build, run and analyze website experiments, with an AI agent interface called PBX and an AI Targeting add-on.
What to know first
Kameleoon sells a priced entry tier, PBX Starter at $495 per month, plus a custom Enterprise plan. PBX stands for Prompt-Based Experimentation: a user describes a test in chat and an AI agent builds the variant. The Starter plan caps experiments at 10 and tracked users at 50,000 per month, so traffic and test volume decide when a team outgrows it. Enterprise pricing and AI Targeting prices are not published.

Who Kameleoon is best for
Marketers without developers
PBX produces variants from a chat prompt and keeps the generated code editable, so a marketer can launch a test and hand the code to a developer only when something needs adjusting.
Teams testing before buying
The 30-day trial needs no credit card and allows 3 experiments, enough to run one real hypothesis end to end before choosing a plan or requesting an Enterprise quote.
European organizations
The privacy policy says personal data is stored on servers within the EU, and Enterprise lists custom data residency and on-premise setup for stricter requirements.

What Kameleoon does
- PBX agent
- Users build and run website experiments by chatting with an AI agent, which writes the variant code in the background. A developer can still open and edit that generated code before it goes live on the site.
- Idea discovery
- The agent scans a page for friction points and ranks candidate experiments with a Predictive Impact Scoring figure, so a team starts from a prioritized list.
- Contextual bandits
- Contextual bandit testing shifts traffic dynamically toward the better-performing variants while a test is still running, instead of holding an even split until the end, which reduces the visitors sent to a losing design.
- Segmentation and safeguards
- The Starter plan lists more than 40 segmentation criteria, holdout groups and sample ratio mismatch detection, which flags uneven visitor assignment that would otherwise quietly invalidate a test result and any decision based on it.
- Mobile and SPA coverage
- Mobile app testing and single-page application support are both listed, which matters for sites built on JavaScript frameworks, where navigation does not trigger a full page load and basic snippets can miss the change.
- AI Targeting add-on
- AI Targeting is sold as a premium add-on and its price is not published on the plans page, so a team that wants predictive audience rules has to request a separate quote beyond the Starter fee.
How Kameleoon handles your data
The privacy policy at kameleoon.com says personal data is stored on servers within the European Union. Data is kept for the time needed for the stated purposes, and the policy notes it may be kept for several days or several years depending on its type. The policy does not state whether customer data is used to train AI models. No security certification is named on the pages opened; the site footer links to a PCI DSS page whose content was not described. Enterprise lists custom data residency and on-premise setup.
Where Kameleoon falls short in practice
- Trial data disappears. Tests and data created during the free trial are not saved when it ends, so a team that wants to continue must rebuild its experiments inside a paid plan.
- Starter ceilings. PBX Starter stops at 10 experiments, 50,000 tracked users a month and a single project, ceilings that agencies, multi-brand groups and busy consumer sites can reach within a few months of regular testing.
- Hidden add-on prices. AI Targeting, other premium add-ons and the Enterprise tier carry no published price, so the real cost of audience-level personalization depends on a sales conversation rather than on the $495 figure printed on the plans page.

Kameleoon: common questions
How much does Kameleoon cost?
PBX Starter starts from $495 per month billed monthly, as of November 2026. A 30-day free trial is available. Enterprise pricing is not published, and the premium add-ons, including AI Targeting, have no stated prices on the pages we opened.
What is Kameleoon PBX?
PBX stands for Prompt-Based Experimentation. A user chats with an AI agent that proposes ideas, builds variants without manual coding and helps analyze results. The code the agent generates stays available for editing, so a developer can adjust or review it.
Where does Kameleoon store data?
The privacy policy states that personal data is stored on servers within the European Union, and the Enterprise tier lists custom data residency and an on-premise setup. The policy does not say whether customer data is used to train AI models, so ask for that.
Is there a free Kameleoon plan?
There is no permanent free plan. A 30-day trial needs no credit card and is limited to 3 experiments, limited credits and tracked users. Tests and data are not saved after the trial ends, so you have to rebuild them on a paid plan.
What are the limits of the Starter plan?
Starter allows up to 10 experiments and 50,000 monthly tracked users, with one project and unlimited users. It includes sequential testing, holdouts and sample ratio mismatch detection. Unlimited experiments, traffic and projects belong to the custom-priced Enterprise tier. Check the add-on prices separately.
