Why over 1,370 teams choose Varify
You do not need to set up new tracking
Your analytics tool already provides all the data you need. Varify uses this directly for result evaluation and completely refrains from its own tracking. This means you don't have contradictory data in your web analytics tool and your A/B testing platform.
Thanks to Varify's BigQuery integration, we have direct access to the GA4 raw data in an A/B testing tool for the first time — without any manual SQL queries.
Why we are cheaper — with the same functions
With other A/B testing platforms, you also pay for results tracking. Varify does away with separate results tracking, saving you money by importing your existing web analytics data into our reporting.
Varify dispenses with its own tracking and makes the price independent of traffic — so we can also serve customers with a lot of traffic and a small budget without sacrificing functionality.
Save yourself the trouble of creating goals
After the one-time connection with your analytics tool, all events and metrics are automatically available in Varify as a goal selection — without manual creation. With fully recorded data, forgotten or new goals can even be added during an ongoing experiment.
After the sunset of Google Optimize, Varify.io seamlessly filled the gap. The simplicity and effectiveness of the tool was a real game changer for us at ConversionKings.
Privacy
Varify does not require any personal data for experiment delivery and does not set any cookies, but nevertheless ensures that test participants are always assigned to the correct variation. Our servers are hosted in Frankfurt, Germany via AWS and Cloudflare and meet the highest security standards — compliant with GDPR, CCPA, HIPAA and revDSG.
Varify offers exactly the functions we need for data-driven and GDPR-compliant optimizations — supported by a competent team that is always on hand.
Beginner-friendly & intuitive
Varify makes creating experiments effortlessly simple: change texts, images, styles and move elements or entire sections. You can also use ready-made campaign boosters such as notifications or exit intent layers to get started right away.
The user-friendly interface combined with powerful functions makes carrying out tests incredibly easy.
For all those who want to delve deeper
Build your experiments flexibly with JavaScript, CSS or HTML — including open APIs for controlling experiments and exporting results. Use provided options such as targeting by CSS selector, data layer entry or create your own rules with JavaScript to target your experiments.
I am particularly impressed by the rapid implementation of the necessary functions, which give us the greatest possible flexibility to implement our projects efficiently and data-driven.
How Varify differs from other A/B testing platforms
****199 €$256 – $479$569 – $1,373Unlike the platforms mentioned, a CRO expert will help you right from the first level contact.
The Growth Plan (VWO), the Growth Plan (Convert) and the Growth Plan (Varify) were compared. The basis was 100,000-250,000 monthly tracked users (MTU) on October 16, 2025 with annual billing. Important to mention: From a higher monthly traffic - such as from 500,000 MTU with VWO or 1,000,000 MTU with Convert - the Growth Plan is no longer available and a change to more expensive plans becomes necessary.
