acceleroi vs Shoplift: Which Shopify Testing Approach Fits Your Store?
acceleroi runs an AI-built, screenshot-checked testing loop for Shopify content and UX tests; Shoplift is a self-serve builder for product page, collection, and full theme or rebrand tests that you build yourself. Pick acceleroi to offload the finding, building, and the checks; pick Shoplift if you want direct, hands-on control over theme-level testing.
Choose acceleroi if you want content and UX tests found, built, checked, and shipped for you inside a flat monthly plan, without touching a theme customizer.
Choose Shoplift if you want to build and run your own tests, especially full theme or navigation rebrands, with AI-generated suggestions to guide what to try.
acceleroi vs Shoplift: feature matrix
Pricing
Starter $299/mo (1 test, stores to about 25k monthly visits) through Scale $2,399/mo (12 tests, 300k+ visits). Extra launches at the plan's own per-test rate ($199 to $299), only when they go live, capped at $7,490 per 30 days. First test built and verified free.
Core $99/mo (up to 50k monthly visitors), Advanced $399/mo (up to 100k), Pro $999/mo (up to 250k). Annual billing equivalents run $74/$299/$699 per month, a 25-30% savings.
acceleroi's first test is free and unused tests roll over. Shoplift offers a 14-day free trial.
Which one for your situation?
Shoplift's theme testing covers full rebrands, navigation, and mini-cart changes in the theme customizer. acceleroi builds individual content and UX variants inside your existing theme, not full theme swaps.
The free audit sizes the leaks in dollars; the Growth plan ($999/mo) builds, checks, and ships up to 3 tests at once.
Shoplift's Core plan ($99/mo, up to 50k visitors) is the cheaper entry point for a merchant who wants to build and run tests themselves.
Both scale to this traffic band. The choice comes down to whether the team wants to build and QA tests itself (Shoplift Pro) or have acceleroi build and check them (acceleroi Pro, 6 tests).
acceleroi's first slice and reversible path back to control handle this without a dedicated in-house tester; the Pro plan covers this traffic band with 6 test slots.
Pros & cons

- First slice of traffic with capped exposure and auto-ramp
- First test built and verified free; unused tests roll over instead of expiring
- A verdict only after a week and enough visitors per side; nothing to configure
- Built for content and UX variants inside your existing theme, not full theme swaps or rebrand-level changes; no price, shipping-rate, checkout, or multivariate testing; Shopify-only
- No public Shopify App Store listing yet
- You approve one 90-day plan, then don't build the variants in a customizer yourself
- Tests product pages, landing pages, collections, homepage, search, and prices, plus full theme testing for rebrands, navigation, and mini-cart
- Lift Assist AI generates feature suggestions from patterns across top brands
- Bayesian predictive analysis predicts test duration in real time
- 4.9 stars across 120 Shopify App Store reviews (September 2026), the highest of the tools compared here
