The best part about this framework is that it gives you full control over your application's front end as well as its back-end logic which makes development much easier than other frameworks out there. It also provides great documentation along with an active community of developers who are always willing to help newbies like me learn more about the tool. I am currently working on developing a real time chat app using webj but have run into some issues while doing so (some bugs). But overall I think webj does a good job at making building apps easy even if you don't know how to code. If you're looking for something lightweight then webj might be what you need. We built our chat app using these tools and we were able to develop features such as user profiles, notifications etc within days rather than weeks.
