A place to talk about WordPress the open source content management system. Also a place to ask for help with WordPress. Don't be rude, don't spam.
Basically, none, unless you count the Gutenberg editor. I do quite like GeneratePress for small sites but it's more framework than builder.
My personal opinion is that it's an error to build a whole second UI on top of an existing UI. Divi, Elementor, all of those - they're so horribly heavy and bloated. Better to get into code and build stuff that's slick, fast and more aligned to "true WordPress".
I agree to a point. But sometimes it the ease of use that matters more. But I have made a plan to use straight Gutenberg on some projects.
Elementor for me!
I use Gutenberg with Stackable block plugin. I got the LTD for Stackable. Currently evaluating Greenshift.
I heard of Gutenberg obv. and Stackable looks cool. Will have to test it out. Never heard of Greenshift.
I quite like Bricks as well, but at work we mostly deliver client websites with Elementor.
I tend to like Elementor. Divi is even bulkier. I want to like straight Gutenberg/Block Editor but it's just not there yet.
Bricks + ACSS + Frames. It takes some getting used to but I love the ultimate control.
