Our customers say it best

We have used VisWiz with great effect for the last year and will continue to expand our usage. In the end, our app must look as intended for each of our many daily deploys and VisWiz is a great way for us to help make sure that is the case. We have received great support and feature requests has been expedited quickly. Two great features are the GitHub PR integration and how easy it is to integrate to a build pipeline – generate the images however you want and then VisWiz will take care of the rest.
Mikael Tönnberg CTO, Carbon Cloud

We have found VisWiz to be easy to setup, easy to use, reliable and very cost-effective. Visual testing using VisWiz helps us detect both usability and functional bugs in our products (a picture is worth a thousand words). We tried various visual testing products, but VisWiz proved by far the most reliable and easy-to-maintain.
Julian Carroll Software Development Manager, RealtyTech

VisWiz has enabled our team to ship new features faster by catching many UI bugs during our integration tests in CI. The introduction of this tool in our testing process was easy to do. Highly recommended!
