Run rigorous A/B tests and personalize every visit on Shopify or any storefront โ no engineers required.
Shoplift is a well-built Shopify app for testing themes: section order, layout blocks, and content structure within your Shopify store. It's simple to use and Shopify-native, which makes it a reasonable starting point. Plenty of brands eventually outgrow it, though, once they want personalization, behavioral targeting, multi-step funnel testing, or segment-specific experiences that Shoplift wasn't built to handle. This guide covers the best Shoplift alternatives for Shopify brands ready to expand what they can do with CRO.
Shoplift handles one specific job well: testing Shopify theme-level changes. If you want to check whether Section A or Section B produces more add-to-carts, Shoplift is clean and straightforward.
The limits show up once brands want to:
That kind of work needs a platform built for broader CRO and personalization rather than a theme-testing app.
CustomFit.ai does everything Shoplift does and adds personalization, behavioral targeting, and segment-level experiments, all without a developer and at the same price point.
Here's what sets it apart from Shoplift.
Its personalization engine lets you show different homepage experiences to new visitors and returning customers. You can serve India-specific content to Indian visitors and international content to everyone else, or personalize based on traffic source, so paid social visitors see a different hero than organic search visitors.
Behavioral targeting triggers experiences based on what a visitor does on your site: number of pages visited, products viewed, time on site, cart value. Shoplift shows the same variant to everyone assigned to a treatment, whereas CustomFit.ai can show different variants to different behavioral segments.
For multi-page experiments, you can test a landing page change alongside a product page change in a coordinated experiment and track conversion through the full funnel, not just on a single page.
There's also campaign-level personalization. When an email campaign drives traffic to your store, you can show visitors a landing page that matches the email's content. This UTM-based personalization sits outside Shoplift's scope.
On D2C results, the numbers are public:
Pricing is $99/month, the same as Shoplift's growth tier, with a 14-day free trial and no credit card required.
VWO is a comprehensive CRO platform that adds heatmaps, session recordings, and funnel analysis to A/B testing. It's more complex and expensive than Shoplift, but it covers the full behavioral analytics stack.
Its advantages over Shoplift come down to a few things. Heatmaps and click maps show where visitors are engaging, session recordings let you watch actual visitor behavior, survey tools support qualitative research, and the segmentation for experiments goes further than Shoplift's.
The tradeoffs against Shoplift are worth weighing. VWO is not Shopify-native, so it requires manual event setup for Shopify tracking, most non-trivial tests need a developer, and pricing starts at $199/month and scales with traffic.
It's best for brands that need behavioral analytics such as heatmaps and recordings on top of A/B testing and are willing to invest in setup and a higher price point.
Convert is a mid-tier A/B testing platform with strong privacy credentials and flexible pricing. It's platform-agnostic and works on Shopify and other platforms.
Where it beats Shoplift: there's no third-party data sharing and EU data residency is available, enterprise plans include unlimited tests and websites, the agency features are good for managing multiple Shopify stores, and it's privacy-compliant by default.
The limits against Shoplift are that it isn't Shopify-native and needs custom event setup, there's no behavioral analytics built in, and personalization features are limited.
It's best for agencies managing CRO across multiple Shopify clients, and for brands in regulated sectors where data privacy is a compliance requirement.
Intelligems is a Shopify-native testing tool built specifically for testing prices, shipping rates, and discount structures, a use case that neither Shoplift nor CustomFit.ai focuses on.
Its strengths are narrow but real: it tests price and shipping changes natively within Shopify, it helps brands find the optimal price point for a product, and it uses Shopify-specific event tracking.
The catch is that the use case is very narrow, limited to price and shipping testing, so it doesn't replace a full CRO/personalization platform and is best used alongside a broader testing tool rather than instead of one.
It's best for brands that specifically want to A/B test their pricing strategy before a product launch or pricing change.
Trident AB is a lower-cost Shopify app for basic A/B testing of product pages and collections. It's simpler than Shoplift and more affordable.
On the plus side, it costs less than Shoplift for basic testing, uses Shopify-native tracking, and has a simpler interface for people brand new to CRO.
The tradeoffs: it's more limited than Shoplift in test types, has no personalization capabilities, and comes from a small vendor with limited support resources.
It's best for very early-stage brands that want to start testing with a minimal monthly investment before graduating to a more capable platform.

Shoplift is a good choice when you specifically want to test section order and layout changes within Shopify's theme editor, your team knows Shoplift's interface well and the workflow is working, you have no immediate need for personalization or behavioral targeting, and you're satisfied with theme-level insights without multi-step funnel experiments. If all of those hold, there's no urgent need to switch.
It's worth looking at a more capable platform when you want to show different experiences to different visitor segments (location, device, traffic source, behavior), when you want your email campaigns to connect to personalized landing page experiences, when you keep testing the same page with similar learnings and need to go deeper, when you want to run personalization alongside A/B testing without managing two separate tools, or when your team is spending more time working around Shoplift's limitations than running tests.
For most brands at that stage, CustomFit.ai is the most natural expansion from theme testing into full CRO and personalization, without changing price points or requiring developer resources.
If you're switching from Shoplift to CustomFit.ai:
You can run both tools at once, but it creates attribution complications, so don't do it longer than necessary.
Clarify your next 90-day testing goals before choosing an alternative. If personalization is on your roadmap, pick a tool that does it; if not, basic A/B testing is fine.
Check pricing at your traffic level. Some tools price per tested visitor, which escalates quickly for high-traffic stores, so CustomFit.ai's flat pricing ($99/month) is easier to predict.
Prioritize Shopify-native tools. Non-native integrations require manual event setup, which opens the door to tracking errors and unreliable test data.
Don't over-engineer it. If you're running 1 to 2 tests per month, you don't need an enterprise platform. Match the tool to your current testing velocity and where you expect to be 12 months out.
