BrowserStack

Overall Opinion: There's no lack of tools out there to help developers create visually appealing and interactive content, but as the features available to web developers become richer and more diverse, there's greater risk that the experience you're trying to create won't be the same for all of your customers. With a wide variety of browsers, operating systems, and devices available, creating a website that's compatible with all of them can be a herculean task. For the longest time, developers and designers relied on the use of virtual machines to simulate user experiences, but these can be a chore to setup and maintain. BrowserStack takes the hassle out of testing your code through the use of an external Selenium grid. BrowserStack is utilized by big name developers like Microsoft, jQuery, and the Wikimedia Foundation, and for good reason. Their Selenium grid lets you test multiple different systems in parallel with one another. That allows you to test compatibility more quickly so you can focus on the task of coding rather than testing your code in different environments. BrowserStack offers support for popular browsers like Internet Edge, Edge, Safari, Chrome and Firefox, as well as a range of portable Android and Apple devices. Altogether, BrowserStack boasts compatibility testing for over 1,100 browser versions. You'll know your customer is getting the experience you want them to have, even if they're running an antiquated version of Windows XP on a dated machine. Parallel processing allows developers the means to run raw tests on multiple browsers at the same time, but there wouldn't be a need for a tool like BrowserStack if there weren't complications in the development process. That's why BrowserStack comes equipped with all the standard development tools an individual needs to stress test their apps or websites. All you have to do to get started is select your operating system and browser within the software, and BrowserStack will automatically create an instance where you can test the compatibility of any website or app. The BrowserStack Local extension for Chrome adds further versatility to the process. Using this, you can complete the debugging and development you need before you ever deploy your app or website online. BrowserStack makes it easy to integrate their functionality directly into your proprietary software. Easy integration is available for over a dozen popular languages like C#, Python, and PHP. If you need an extra level of security during the testing process, BrowserStack has you covered. The BrowserStack tunnel gives you the security you need even when testing in internal development environments or behind firewalls. Larger customers can make use of BrowserStack's enterprise subscription, which presents a whole range of additional features like scalability and priority customer support.
