Run rigorous A/B tests and personalize every visit on Shopify or any storefront โ no engineers required.
Google Optimize was shut down in September 2023, which left millions of websites that had relied on it for free A/B testing without a replacement. Three years later, in 2026, the market has consolidated around a clear set of alternatives. Some are free-ish, most are paid, and a handful are purpose-built for ecommerce. This guide ranks the best Google Optimize alternatives by how they perform for the most common use cases: ecommerce optimization, landing page testing, and general website CRO.
Google Optimize's appeal was simple. It was free, it integrated natively with Google Analytics, and it had a basic visual editor that non-developers could use. Its limitations were real too:
When it shut down, most of its users were small and mid-size businesses that needed something affordable, simple, and connected to Google Analytics. The alternatives below address that need at various price points.
| Tool | Best For | Starting Price | GA4 Integration | Shopify Support |
|---|---|---|---|---|
| CustomFit.ai | Shopify D2C ecommerce | $99/mo | Yes | Native |
| VWO | General website optimization | $199/mo | Yes | Partial |
| Convert.com | Privacy-conscious teams | $199/mo | Yes | Partial |
| Unbounce | Landing page testing | $99/mo | Yes | No |
| Crazy Egg | Heatmaps + basic testing | $49/mo | Yes | No |
| AB Tasty | Mid-market brands | ~$2,000/mo | Yes | No |
| Microsoft Clarity | Free heatmaps only | Free | Partial | No |
Google Optimize was never purpose-built for ecommerce. CustomFit.ai fills that gap for Shopify brands with native integration, ecommerce-specific metrics, and no-code operation.
Google Optimize required you to manually set up conversion goals (usually via GA events) to track ecommerce metrics. CustomFit.ai tracks add-to-cart, conversion rate, AOV, and RPV automatically, with no setup required, because it reads directly from Shopify's event stream.
The visual editor does more than Google Optimize's editor did. You can modify any element on your product pages, collection pages, homepage, and cart, then preview changes on your actual store before going live.
Compared with Google Optimize, the notable advantages are:
Pricing is $99/month for Starter and $249/month for Growth, with a 14-day free trial and no credit card required.
Best for Shopify ecommerce brands that want to replace Google Optimize with something that does more but stays accessible to non-developers.
VWO is the most popular paid Google Optimize replacement, and for good reason. It covers the full range of optimization tools (A/B testing, multivariate, split URL, heatmaps, session recordings) in one platform.
Its main strengths are self-serve onboarding without sales involvement, combined testing and research tools in one subscription, solid documentation and support for teams new to CRO, and GA4 integration for importing test results.
Pricing starts at $199/month for basic testing and scales with traffic. Heatmaps and session recordings require higher tiers.
Best for general website optimization teams that want one CRO tool covering everything and don't need Shopify-specific features.
The limitation: for pure Shopify optimization, VWO requires workarounds that CustomFit.ai handles natively. See our full VWO alternatives guide for context.
Convert.com was one of the first "GDPR-friendly" A/B testing platforms. It doesn't collect or share visitor data with third parties, it uses session-based tracking without persistent cookies by default, and it stores data in EU infrastructure.
Its strengths are a strong privacy posture that matters for brands serving EU customers, solid A/B and split URL testing, reasonable pricing for the feature set, and good GA4 integration.
Pricing is $199/month for 800k monthly tested users.
Best for brands with European audiences or strict data compliance requirements. It also works well for CRO agencies managing multiple client accounts.
The limitation: most non-trivial tests need developer involvement. It isn't plug-and-play for ecommerce without technical support.
Unbounce is a landing page builder with built-in A/B testing. It doesn't optimize your existing website. Instead, you build landing pages in Unbounce's drag-and-drop editor and test variants there. If you're running Google Ads or Meta campaigns to dedicated landing pages, it's a strong choice.
Its strengths are Smart Traffic AI that routes visitors to the highest-converting variant, a large library of conversion-optimized templates, A/B testing built into the page builder, and an easy GA4 connection for attribution.
Pricing is $99/month (Build) and $149/month (Experiment with A/B testing).
Best for performance marketing teams that want to test multiple ad landing page variants quickly.
The limitation: it can't optimize your main Shopify store, only standalone landing pages. It isn't a full Google Optimize replacement for on-site testing.
Crazy Egg combines heatmap analysis, session recordings, and basic A/B testing at an accessible price point. For teams that mainly used Google Optimize for small-scale testing and want to add research tools, Crazy Egg is a reasonable upgrade.
Its strengths are heatmaps and scroll maps to diagnose conversion problems, session recording to understand visitor behavior, basic A/B testing (limited to page-level variations), and a low starting price.
Pricing is $49/month (Basic), $99/month (Standard), and $249/month (Plus).
Best for small ecommerce teams in the early stages of CRO that want research tools alongside basic testing.
The limitation: the A/B testing is limited, so it isn't suitable as the primary platform for a serious experimentation program.
Microsoft Clarity is worth mentioning because it's free and includes heatmaps and session recordings, features Google Optimize never had. It has no A/B testing capabilities at all, though.
Its strengths are that it's completely free with no session limits, it offers heatmaps, click maps, and session recordings, it integrates easily with GA4, and it works well for initial diagnostic research.
Pricing is free.
Best for supplementing your A/B testing tool with free heatmap research. Use it alongside CustomFit.ai or VWO.
The limitation: it isn't an A/B testing tool at all, so it can't replace Google Optimize for experimentation.
Most D2C brands that used Google Optimize need two things: a way to understand where visitors drop off (research), and a way to test fixes (experimentation). Here's the recommended stack at different budget levels.
On the budget tier (under $100/month), pair CustomFit.ai Starter ($99/month) with Microsoft Clarity (free). You get native Shopify A/B testing and AI personalization alongside free heatmap research.
On the growth tier ($100 to $300/month), use CustomFit.ai Growth ($249/month) for testing and personalization, with GA4 for behavioral analytics.
On the scale tier ($300+/month), add a dedicated data analytics tool (like Mixpanel or Amplitude) to CustomFit.ai for cohort analysis and LTV tracking.
