You can easily integrate with other systems like Jenkins, Selenium etc to automate your tests in few clicks without writing any code or scripting language. It's free but it supports only BDD/Cucumber frameworks at this point of time which I think will be very helpful when it comes down to implementing agile development practices where developers use them as well. We are automating our web applications using Cuke4Docker toolkit from qeantine pace. This has reduced manual effort significantly while developing new features by reducing number of bugs found during final release stage.
