Outtest vs Kameleoon
Kameleoon and Outtest both put AI at the center of testing, but they split the work differently. Kameleoon's PBX lets you describe a change and have AI build the variant, and PBX Ideate suggests what to test. Your team still picks the ideas, sets goals and reads the stats. PBX Starter starts from $495 a month for 10 experiments and 50,000 visitors, and Enterprise adds feature flags, mobile app tests and personalization.
Outtest is a new AI split tester for small teams without a CRO specialist or developer time. Its agents find the funnel leak, build the version, run it and call the winner, and every test is judged on revenue per visitor read from your payment tool. It costs $29 to $499 a month by tests per month. Outtest has no track record yet and doesn't list feature flags or mobile app testing.
