If we talk about Applitools, then I would say they have made Visual Testing very easy.
They supports multiple languages and while using Applitools, you don’t have to create new test cases. They shall automatically integrate their code within your test cases.
I won’t say this is the only place where you can perform automated Visual UI Testing. LambdaTest also offers you to perform Visual UI Testing. It also supports multiple languages and it’s automated so you don’t have to design your test cases. While you perform it at LambdaTest, you can also check the Responsiveness of your Website and compare it to other websites at the same time.
