I love that this tool is free for personal use as well as commercial usage. It's simple yet powerful and can be used in many different ways. The documentation could be better so it would take less time to get familiar with its features. Also, there are some issues when using this tool since you have to install Java 8 or above which is not always compatible. Try out other options if you're looking for something more lightweight but still capable of handling your needs. We've been able to easily handle all our testing by implementing Selenium tests.
