Tools for performance testing

You can be fine with online website testing services – they will show you the speed of the page load, how people see your site from different locations, and so on. The more different manual website testing tools you use, the more you will be able to improve.

Today I decided to collect for you the best tools for testing sites on mobile operating systems such as iOS and Android, without the need to use physical devices. These tools will help you test the functionality and adaptability of your sites on various mobile platforms.

Below I want to give you a small selection of mobile emulators, as well as other tools for testing and validation on various mobile platforms. These tools will help you identify the problem areas of your website and take appropriate action.
