Outtest vs VWO
VWO, now sold under the Wingify name, is a full optimization suite. It has a visual editor, Bayesian reports, heatmaps and session recordings, personalization, feature flags, and Wingz AI agents that draft hypotheses and variations for your team to approve. Prices come from a sales quote based on your monthly active users.
Outtest is a new, narrower tool for small teams without a CRO specialist or developer time. Its AI agents find the biggest leak in your funnel, build the version, run the test and call the winner, and each test is judged on revenue per visitor read from your payment tool. Plans run from $29 to $499 a month by tests per month. Outtest has no track record yet, and it doesn't list heatmaps, session recordings or feature flag SDKs.
