Pick Intelligems if you want to test prices, shipping thresholds and offers, not just page layouts, and you have someone who will run tests regularly. Pick Shoplift if you mainly test themes, templates and PDP layouts and want something you can leave installed. Pick Dynamic Yield if you are an enterprise with a merchandising team, multiple regions and a budget for a personalization platform, not just a test tool. If nobody owns testing internally, none of the three will pay for itself.

Intelligems
Intelligems is the one of the three that will test things other than layout. Price points, free shipping thresholds, discount depth, bundle pricing, offer copy. That matters because the remaining upside on a storefront that has already settled its layout questions sits in what you charge and what you throw in.
It reports on margin and profit, not just conversion rate, which is the right frame when a test that lifts conversion can still lose money. Brands that use it seriously tend to run a test calendar and have one person who owns it.
Two complaints come up. The first is price: it is not a cheap app, and if you ship only a couple of tests a quarter the math stops working. The second is mechanical. Price testing on Shopify often means duplicating products, and duplicate variants annoy everyone downstream, including the people managing your feeds and your ERP. Ask how the tool handles that before you sign.
You can see Intelligems on storefronts across categories, including 1st Phorm, Aviator Nation and BRUNT Workwear.
Shoplift
Shoplift is the simplest answer for theme-level testing. Duplicate a theme, change the PDP or the homepage, split traffic, read the result. Setup is short, and brands tend to leave it installed and switch it on when they have something to test.
That is also its limit. It tests pages, not prices. And the failure that comes up is not the product: teams buy it, run a couple of tests, then stop because nobody has time to build variants and read results. If testing is a side job for someone already running merchandising and email, expect the tool to sit idle.
One thing to plan for: holdout testing and measuring anything that spans sessions is harder with page-level split tools than vendors imply. If you need to prove incrementality across a whole program rather than a single template, work out the measurement plan before you commit.
Dynamic Yield
Dynamic Yield is a personalization platform with experimentation inside it, sold to enterprise. It handles segmentation, audience rules and recommendations across a large catalog and multiple markets, which neither Shopify-native tool is built for.
The pattern on the way out is consistent. It is expensive, it needs real implementation effort, and brands that bought it for personalization can end up running what amounts to simple A/B tests on button and copy variants. If the output is a different color button, you have paid an enterprise price for a Shopify app's job.
It earns its place when you have a merchandising team that will build and maintain segments, enough traffic for segment-level tests to reach significance, and a catalog wide enough that personalization changes what people see rather than how it looks.
How to decide
A practical sequence for mid-size Shopify brands: start with theme testing to settle layout questions, then move to price and offer testing once the obvious page work is done. That order is why the move from theme testing to Intelligems is more common than the reverse.
If you are also weighing recommendation and personalization tools, the overlap is covered in Nosto vs Algolia vs Rebuy vs Dynamic Yield.
Questions people ask
Is Intelligems worth it for a smaller Shopify store?
Only if you will run tests regularly and have enough traffic for results to mean something. The value sits in price and offer testing, and that takes volume. Smaller stores often get more out of a cheaper theme-testing tool until traffic supports margin tests.
Can Shoplift test prices?
Shoplift is built for theme and template split testing, not pricing. If your test roadmap is mostly price points, shipping thresholds and discount structures, that is Intelligems territory.
Why do brands move off Dynamic Yield?
Cost against delivered value. It needs implementation work and ongoing segment maintenance, and brands that do not staff for that can end up running simple page tests at enterprise pricing. Those brands tend to move to a Shopify-native test tool.
