Page builders made WordPress easy to design in. Many sites are still built that way, and some of them run well.
The trouble comes when the builder is the whole site. Divi 4 and WPBakery store every layout as shortcodes inside your content, so switching them off fills the pages with code in square brackets. Elementor keeps its layouts in its own data, and the site now mixes sections, containers and, since 2026, its new atomic elements. Add-on packs fill the gaps, each with its own licence and update.
Divi 5 now stores pages in a new format, so a Divi 4 site faces a conversion either way. That’s a good moment to decide whether the builder should stay at all.
