UPDATE: I tried their AI assisted builder. After inserting a single paragraph Brizy built a site in seconds. I'm quite impressed. Shortening the time to generate a quick site is a valuable tool to have..
Brizy is an excellent builder, focused almost exclusively on the ease of use. I took one star off because it lacks (1) e-commerce capabilities (an absolute must nowadays even at entry-level) and (2) cloud pages are slower than desired to load, especially after updates.
Brizy building blocks are excellent otherwise, and I wish I could use CSS with less code headache, as in frontend functions to adjust instead of having to bring my own code.
I do not use Brizy WP so I cannot comment on that, but their Cloud version is my favorite builder even with the two aspects I mentioned above.
One function I would love to see implemented, is the option to design MOBILE-first. Right now, the desktop version takes precedence. I would like to be able to choose when I start designing, a website for Mobile and as such the main builder would be on Mobile format.
Right now there a bit too much friction between the three versions, and the builder does not automatically help 100% in converting a site well between desktop and mobile (not without sufficiently heavy intervention).
As per AI, my expectations are logistical not creative. I want to be able to say "convert this desktop site to a mobile-friendly site" and that's where my work should end.
Overall, Brizy is a really great option and a time-saver!
