We have worked with an agency for A/B tests for a long time — since Varify, we do it completely ourselves. The reason: the AI function. More complex tests, which would have previously required developer time, I now implement independently. I describe what I want to test, the AI generates the code. For smaller companies, this is a real game changer. A/B testing was long a discipline that one had to "afford." Varify + AI makes it accessible — anyone with a hypothesis can test it themselves today. Review collected by and hosted on G2.com.

The evaluation is currently running via GA4 — this requires clean, error-free tracking. In practice, there are always gaps, which can quickly make the test results unreliable. A more independent evaluation directly in Varify, independent of GA4, would be a big step forward. Review collected by and hosted on G2.com.

Pricing is great and functions are as well really nice. I do not miss anything and for us with small budget and not many people its possible through varify.io making CRO better. Review collected by and hosted on G2.com.

Sometimes loading times are long, would be happy if its faster Review collected by and hosted on G2.com.

Varify.io® has truly become our all-in-one, "worry-free" platform for A/B testing. What I love most is the radical simplicity combined with powerful flexibility. The absolute gamechanger for us is the new Varify MCP (Model Context Protocol) integration. Being able to control, spin up, or analyze A/B tests directly through AI agents like ChatGPT or Claude via chat saves us hours of manual dashboard clicking every week.

The UI/UX is incredibly clean and intuitive, allowing non-technical team members to easily build variants in the visual editor. Furthermore, the seamless integration with our existing web analytics (serving as our single source of truth) is fantastic. Combined with their highly competitive flat-rate pricing and zero traffic limits, it offers an unmatched ROI. Review collected by and hosted on G2.com.

There is honestly very little to complain about because the platform is incredibly stable and the team ships updates at a very fast pace. If I had to nitpick, I would love to see even more pre-built best-practice templates in the visual editor or even deeper documentation for niche edge cases regarding the MCP setup. However, given how quickly the platform evolves and how responsive their support team is to feedback, this is complaining at a very high level. Review collected by and hosted on G2.com.

Varify.io is very easy to set up and use. It has all the functions that are useful in A/B testing. What I really like is the fast and straightforward support. I can enter my problem or question in the chat and shortly after, I receive a personal response via email from a staff member. So far, all issues have been resolved quickly.

I have no difficulties with the tool. Everything works, and if there are any questions, they are answered quickly. Review collected by and hosted on G2.com.

Ich finde Varify.io® sehr einfach zu bedienen. Selbst als jemand, der nicht tief in der Technik steckt, kann ich die Auswertung sehr gut lesen und mir dann überlegen, welche nächsten Tests ich umsetzen möchte. Wir können mit mehreren Personen aus verschiedenen Bereichen wie Marketing, Newsletter und Sales gleichzeitig mit Varify.io® arbeiten. Es hilft uns schnell und unkompliziert, Banner zu platzieren und verschiedene Creatives zu testen, um die beste Bannerwerbungs-Conversion-Rate zu erzielen, und das kann ich komplett alleine machen. Außerdem war die anfängliche Einrichtung sehr gut und einfach möglich, mit einem hervorragenden Onboarding-Flow, was unser Technik- und Marketingteam zufriedenstellt.

Loads super fast, i.e., minimal flicker. Predictable pricing - flat fee (instead of paying more for more traffic). Easy to use. And the team keeps investing in making the product better. Review collected by and hosted on G2.com.

Candidly no downsides, but if I had to draw a contrast, it doesn't come with its own analytics - you have to plug it into whatever tool (e.g., GA4) you have. Review collected by and hosted on G2.com.

I really appreciate the team at Varify.io® and the results we achieve. The team is highly adaptable, responds quickly to our needs, and works collaboratively with us to find the best solutions. I especially value the easy collaboration, fast communication, and the flexibility of the team. Varify.io® allows us to test ideas quickly and implement optimizations efficiently. Apart from the good results, I particularly like the partnership-like cooperation. It feels like the team truly thinks along with us, addresses our needs, and develops the best solutions together with us. The initial setup was very simple and straightforward. The integration was quick to implement, and with the great support from the team, the whole process went smoothly. Review collected by and hosted on G2.com.

There are no major things we dislike about Varify. Of course, there are always additional features that we would like to see in the future, but the flexibility and support from the team make up for a lot of that. Review collected by and hosted on G2.com.

What I like most about Varify.io® is the combination of ease of use, high flexibility, and the strong focus on the needs of modern e-commerce teams. New A/B tests can be quickly created and published without requiring developer resources for every change.

I am particularly impressed by the seamless integration with GA4 and the ability to evaluate experiments cleanly and data-driven. The performance is also excellent – the tool works with a lean snippet and has no noticeable impact on loading times.

Another big plus is the team behind Varify.io®. New features are continuously developed, customer feedback is taken seriously, and support responds quickly, competently, and solution-oriented. Overall, from my perspective, Varify.io® offers excellent value for money and is a clear recommendation for companies that want to conduct professional A/B testing.

There isn't much to dislike, but I'd love to see even more native integrations with third-party tools and analytics platforms. While the current feature set already covers everything we need for A/B testing, a few additional advanced reporting and collaboration features would make the platform even stronger for larger teams. That said, the product is evolving quickly, and the team is very responsive to customer feedback, so many improvements are implemented over time. Review collected by and hosted on G2.com.

As a CRO agency managing multiple clients, Varify has become our go-to A/B testing platform. When we switched from Kameleoon, the key reasons were GDPR compliance and servers located in Germany. Crucial for our European clients where data privacy is non-negotiable.

The visual editor allows us to build and launch tests quickly across different client projects without always needing dev resources. The BigQuery integration connects seamlessly with our analytics workflows, and test performance is excellent – no negative impact on client page load times!

What really stands out for agencies: we can manage tests for multiple clients efficiently, and the cookieless tracking means we don't have to deal with consent banner complications. The unlimited tests pricing model is perfect for our use case. We can run as many experiments as needed without calculating costs per client.

Support has been responsive whenever we had implementation questions, and onboarding new team members is straightforward. Review collected by and hosted on G2.com.

Honestly, there's not much to dislike. It would also be nice to have a few more pre-built templates for common test scenarios, but the visual editor is flexible enough that this isn't a real limitation. Review collected by and hosted on G2.com.

What's really cool about Varify.io is how simple everything is. You can set up A/B tests and your own pages really quickly without much prior knowledge. The visual editor is awesome because I can throw my ideas right in there and bam, it’s done. And the support is awesome. Review collected by and hosted on G2.com.

Honestly, it would be nice if there were more integration options. It's good as it is, but more would be better. But there are more comming soon, I was told. Review collected by and hosted on G2.com.
