Using Browserling, I never had a bad surprise. this tool is responsive and always offers the latest versions for each browser. I particularly recommend live testing which allows you to directly test the site and generate a screenshot if you have detected a bug or an anomaly in your interface. PS: I will give it 10/10 when recording videos of browsing sessions will be ready.
Before, I received a lot of bad feedback from my users because my site was not compatible with certain browsers and operating systems. but now with TestingBot I can automatically test my website with the most used systems and fix these bugs and avoid losing customers. TestingBot integrates with the most popular continuous integration platforms such as Jenkins, TeamCity, GitHub Actions, and more. The browser and device grid are compatible with Selenium, Appium, Cypress, and other frameworks.
For quicker and safe testing I always choose Browserling. It's also my best tool for responsive testing, as it allows me to resize the window and see how my interface looks in different screen resolutions. Browserling is better than others in manual testing because it has more features than others.
I chose TestingBot because it is easier to install on my site as well if you compare it with other testing services that I have known. Also, the live interactive testing is very fluid with TestingBot which was not the case with the other tools.
