Outtest vs Google Optimize
You can't choose Google Optimize any more. Google closed it on September 30, 2023, so this page compares what Optimize did with what Outtest does, for anyone still replacing it. Optimize was free, ran on Google Analytics, and gave you a visual editor and Bayesian reports. You planned, built and judged every test yourself, usually on Analytics goals.
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 from your payment tool rather than Analytics goals. It connects read-only to Google Analytics as well as payment tools like Stripe and Shopify. It costs $29 to $499 a month, so unlike Optimize it isn't free, and it has no track record yet.

Pick Google Optimize if
- You can't any more. Google shut Optimize down on September 30, 2023.
- If you ran app experiments, Firebase A/B Testing still works; Google kept it running after Optimize closed.
- If you want a tool Google named as an Analytics testing partner, look at AB Tasty, Optimizely or VWO. AB Tasty and VWO merged into Wingify in 2026.
- If you want the same hands-on visual editor, Convert, VWO and Optimizely all have one.
Pick Outtest if
- You used Optimize because it was free and simple, but never had time to plan and read tests. Outtest's agents do that part.
- You want tests judged on revenue per visitor from Stripe, Shopify or another payment tool, not on Analytics goals.
- You want a low, published price: $29 a month for 3 tests.
- You still use Google Analytics. Outtest connects to it read-only.
The verdict
Google Optimize is gone, so the real choice is what replaces it. Google didn't build a website replacement; it pointed users to third-party tools. If you have a CRO person and want hands-on control, a tool like Convert or VWO gives you a visual editor. If you'd rather have AI run revenue-judged tests for $29 to $499 a month, Outtest fits, with the caveat that it's new.
Questions people ask
When did Google Optimize shut down?+
September 30, 2023. Google announced it in January 2023, and Optimize and Optimize 360 stopped that day, along with any experiments still running.
Why did Google shut down Optimize?+
Google said Optimize lacked many of the features and services customers asked for in experimentation, and that it would invest in third-party A/B testing integrations for Google Analytics instead.
What did Google recommend instead of Optimize?+
Google said it was building Google Analytics integrations with AB Tasty, Optimizely and VWO, and made its APIs public so any testing tool can integrate. AB Tasty and VWO merged into Wingify in 2026.
Is there a free Google Optimize replacement from Google?+
Not for websites. To A/B test with GA4 you use a third-party tool to run the test and read the results in Google Analytics. Firebase A/B Testing still covers apps.

Google didn't publish a price. Optimize 360 was sold through Google's sales team and invoiced monthly. The free version of Optimize cost nothing.
