Google Optimize Alternatives: Best Alternatives to Google Optimize, Replacements and 2026 Pricing Compared

Short answer: there is no single Google Optimize replacement, and Google never shipped one. In August 2026 the practical picks are GrowthBook or PostHog if you want a genuinely free tier and have an engineer, Convert Experiences at $299 a month billed annually if you want a marketer-operated tool that publishes its full price list, Optimizely or VWO if you are buying through procurement, and Microsoft Clarity if what you actually needed was to see where people struggle rather than to run a test. Google named three official successors when it sunset Optimize. Two of them have since merged into one company and none of the three publishes a price today.

What happened to Google Optimize, in Google's own words

Google Optimize and Optimize 360 stopped working on September 30, 2023. Google's support page states that "any experiments and personalizations still active on that date have ended," so there was no read-only wind-down and no data export grace period after the fact. The reason Google gives is unusually direct for a sunset notice: Optimize "did not have many of the features and services that our customers request and need for experimentation testing."

One piece of Optimize did survive, in a place most people never look. Firebase A/B Testing ran on Optimize infrastructure for inference on every experiment started on or before October 23, 2023. Experiments started after that date use frequentist inference and no longer touch Optimize at all. If you run mobile experiments through Firebase, nothing broke.

Google named three official successors. Two are now the same company.

This is the part almost no comparison page mentions, and it is the single most useful thing to know before you shortlist. When Google announced the sunset it did not simply walk away. Its help page says, verbatim, that "we are collaborating on integrations with the following A/B testing providers (listed in alphabetical order): AB Tasty, Optimizely, VWO." Three named vendors, in alphabetical order, presented as the sanctioned path forward.

Here is what has happened to that list since.

So the three-vendor recommendation is now two companies, and the count of them that will show a self-serve buyer a number is zero. A team that took Google's advice literally in October 2023 and picked VWO for its free Starter plan has since watched that plan get scheduled for closure and the price list come down. That is not a knock on any of the three. It is a description of what happened to the category, and it is why so much advice on this topic reads as confidently out of date.

Google Optimize alternatives compared on published August 2026 pricing

Every figure below was read off the vendor's own pricing page in August 2026. Where a vendor publishes nothing, the row says so rather than repeating a number from a third-party roundup.

Who will actually show you a price

Sort that table by one question and it separates cleanly. Optimizely, VWO, AB Tasty, Adobe Target and Kameleoon publish no price. Convert, GrowthBook, PostHog, Statsig, LaunchDarkly and Microsoft Clarity publish a full one. The split tracks almost perfectly with whether the product is sold to a marketer holding a company card or to a procurement team holding a contract.

That matters more than it sounds when you are replacing Optimize specifically, because Optimize's defining trait was that you could start using it on a Tuesday afternoon without asking anyone. Half of the modern shortlist cannot be evaluated at all without a discovery call, and the two vendors Google itself pointed at are both on that side of the line now.

The free replacement problem nobody states plainly

Optimize was three things at once: free, visual, and operated by a marketer without a developer. Every free option on the market in 2026 gives you at most two of those three.

Read the columns together and the conclusion is uncomfortable but true: there is no longer a free, marketer-operated, visual A/B testing tool. Every free option is engineer-shaped except Microsoft Clarity, and Clarity cannot run a test. If you are searching for a free Google Optimize alternative because Optimize was free, the honest answer is that the specific combination you are looking for stopped existing, and the closest substitutes ask you either for money or for developer time.

Convert Experiences is the one that still publishes the whole table

Among tools a marketer can drive without an engineer, Convert is the outlier worth understanding, because it publishes not just tier prices but the overage rates almost nobody in this category discloses. Verified at the pricing page in August 2026.

Two things in that table repay a second look. First, the advertised annual saving is not flat: it is 25 percent on Growth and 30 percent on Pro, so the higher tier rewards the commitment more, which is worth checking on any vendor that advertises a single "save X percent" line. Second, the overage rate falls as you move up. Growth overage works out at $3.99 per 1,000 extra tested users and Pro at $2.80, so a team that regularly spills over its 100,000 allowance is paying a premium to stay on the cheaper plan. Convert also lets you switch overage billing off entirely rather than surprising you.

One more detail on that page is a market signal rather than a price: Convert lists "FREE VWO Migration" as a headline feature on both paid tiers. Vendors do not build migration offers for platforms nobody is leaving.

Can you A/B test in Google Analytics now?

Not natively, and this trips people up constantly. GA4 has no built-in experiment builder that replaces what Optimize did. What Google actually did was open the door for other people to build it: its help page notes that "we have made our APIs publicly available so anyone can integrate their A/B testing tool with Google Analytics." So the modern pattern is that you run the test in a third-party tool and report on it in GA4, which is exactly the arrangement Optimize existed to save you from.

Before you buy anything, check whether you have the traffic

This is the section most vendor-adjacent roundups leave out, because it sometimes ends with "do not buy a tool." A two-way test needs roughly 1,000 conversions per variation to detect a modest lift with confidence. On a page converting at 2 percent, spotting a 10 percent relative improvement takes on the order of 50,000 visitors per variation.

If you are in the first band, and a great many sites searching this query are, the money is better spent on the diagnosis than on the split tester. That is the gap our landing page audit was built for, and it is the honest recommendation more often than a tool comparison page is supposed to admit.

What the roundups get wrong about Google Optimize alternatives

Where Converto fits, and where it does not

Converto is not a replacement for the testing engine. It replaces the step that came before it, which is the step most teams were actually stuck on. Optimize gave you a blank variant editor and a statistical readout. Deciding what the variant should say was always yours to solve, and a split tester with nothing to test is an expensive dashboard.

Paste a live URL and Converto scores the copy, layout, CTA placement, page speed and AI-readability, then writes ready-to-ship headline and CTA variants you can push into whichever tester you land on. Nothing to install, works on pages you do not own so you can audit a competitor, and self-serve from $19 a month. Suggestions are data-informed rather than guaranteed, and if you are in the under-10,000-visits band above, it is the whole program rather than a supplement to one.

If you are still narrowing the field, our A/B testing tools comparison goes deeper on the client-side versus server-side split that decides most shortlists, best VWO alternatives covers the vendor Google pointed at that has changed the most, best Optimizely alternatives covers the enterprise end, and best CRO tools is the wider category map. The single-vendor page on the Google Optimize alternative question covers how Converto compares head to head.
