As much as I admire and acknowledge your response, you are simply wrong. Wappler’s use of the Bootstrap 4 Framework offers a much better responsive structure for its apps than Bubble’s current system. Although Bubble’s responsive structure gives you a lot of control, there are some HUGE limitations - have a look at this post: Collapsable Width
Furthermore, I’m not sure I quite understand what you are saying about speed, however, what I can assure you is that Wappler is much faster than Bubble in terms of page speed, data creation, data modification and data deletion. I did a page speed test between a complex Wappler website with lots of traffic/data (https://www.eliasimoveis.com.br/) and a Bubble template with barely any traffic/data (https://thefreelandingpage.bubbleapps.io/) and the load times were 1-2 seconds and 5-8 seconds respectively.
For you to say Wappler is similar to Wix just shows that you really haven’t done your research. Wix is mainly used for static landing/marketing pages and hasn’t got the ability to create complex applications such as SaaS applications like Bubble or Wappler.
I am by no means saying I prefer Wappler to Bubble (as of yet 
), in fact, I prefer Bubble’s canvas style approach and even think it’s genius, as it gives the user more freedom to build and design apps, as opposed to Wappler’s drag-and-drop style approach. All I am saying is that we should not turn a blind eye to the competition. I’ve seen companies go bust because of this - mine included! As a Bubble fan, I’d want to see Bubble implement some of the above features Wappler has.
