Varify Software GmbH · Germany · since 2019
German flat-rate A/B testing platform for mid-market shops and CRO agencies that already run GA4 and refuse to pay per tracked user, results are read from your own analytics stack.
Best for High-traffic EU stores that want a predictable monthly bill
The verdict
Varify is the cheapest way to test a busy store: a flat rate from €199 per month with unlimited tracked users, so a traffic spike never turns into an invoice. It installs by snippet without an app, imports Shopify orders and revenue into its dashboard, and documents price, theme and template tests on the storefront. Checkout testing exists, but as a separate app at $119 per month on top, and only on Shopify Plus. The entry plan runs one-sided statistics by default and every plan covers one domain, which multi-brand and multi-country merchants will feel.
Rating by Drip Trading GmbH, the company behind Apex by Drip. How we rate and weight
Strengths
- Flat rate with unlimited monthly tracked users on every plan, removes the biggest cost driver of VWO/Convert/Optimizely-class tools for high-traffic shops.
- No second source of truth: results are computed in your own GA4, BigQuery, PostHog or Shopify data, so testing and analytics numbers cannot disagree.
- Strong EU privacy story: German entity, AWS Germany, cookieless by default, DPA included, documented Consent Mode setups.
- Fast-moving public roadmap: server-side API (Apr 2026), MCP server (Jul 2026), Shopify checkout app, Adobe Analytics integration.
- Highly rated in DACH: 4.8/5 from 103 OMR reviews, with support quality named repeatedly.
Weaknesses
- One domain per plan on every tier, multi-brand and multi-country setups must negotiate "on request", even on Enterprise.
- Tight entry plan: Growth caps at 5 active experiments and locks Bayesian stats, CSV export, APIs and staging environments behind Pro.
- The default statistics are the aggressive option: one-sided tests ship as default, and two-sided tests require Pro, the cheapest plan is the most likely to over-call winners.
- No sequential/always-valid testing and no sample-size planner, peeking discipline rests on advice, not math.
- AI features and Shopify checkout testing are metered extras: AI credits sold separately, checkout app $119/month on top and Shopify Plus only.
- No SOC 2 or ISO 27001 certification yet, which blocks some enterprise procurement.
