Sauce Labs

I am looking to purchase one of these tools for Mobile testing for my team. It should support Native, hybrid, and responsive app testing. It should also feature debugging, parallel execution, automation testing/easy integration with automation testing tools like Selenium, and the capability to provide availability of devices specifically for us to use at any time with good speed of performing all these activities.

I have already used Perfecto mobile, and Sauce Labs in my other projects before. I want to know how different or better is AWS Device farm in usage and how advantageous it would be for us to use it over other mentioned tools

I am working on #OpenSource file uploader. The uploader is the widget that other developers embed in their apps. It should work well in different browsers and on different devices. BrowserStack and Sauce Labs help to achieve that. I can test the uploader in many varieties of browsers+OS only used my browser without virtual machines.

Browser testing grid and test automation so we don't need the servers to do it. Integrates with CI. Sauce Labs
