We use a lot of ajax when the actual page builder is in use, but we do our best to ensure that page load times for published pages are low as possible.
Outputting lean and efficient auto-generated markup (relative to what was out there) was one of our big goals from the start.
We have a free version of the software in the WordPress repo: https://wordpress.org/plugins/beaver-builder-lite-version/
You can demo the tool, peek at the markup, and see how it well it plays with your WP theme/install with the free version.
I'll try out the lite theme and hopefully find it fitting to our site. Once again, thanks for replying to my off-topic comment. I just had to take the chance since i've been considering your product lately!

I have a product in a similar space, Beaver Builder (https://www.wpbeaverbuilder.com). A few differences being that it's an in-browser tool and it's a WordPress plugin.
Who is your target customer? Are you hoping to improve workflows for frontend developers or enable non-developers to build web pages? Also, what are your thoughts on maintaining a Bootstrap Studio site?
FWIW, we hit a nice niche with freelance web designers and web agencies. Drag and drop streamlines the development process and it also enables more tech-savvy clients to jump in and make their own edits and updates.
