I like that it's open source, free to use (if you are able). It is also very easy for anyone who knows how computers work and has programming skills or can teach themselves quickly enough. They need more documentation because there isn't much out in terms of tutorials/guides yet but they do offer support through Slack community which helps. The UI could be improved as well by having additional features such as adding links directly without going back into main dashboard first. But overall this tool really does help me test my web applications before releasing them!
