Yes, absolutely! Mold Blocks is designed to work seamlessly with Full Site Editing (FSE) themes in WordPress. Since it’s built for the Gutenberg editor, it integrates smoothly into FSE workflows—whether you’re editing templates, blocks, or global styles. You can use Mold Blocks within block-based themes, customize layouts directly in the site editor, and even apply styles that respect your theme’s design system. It’s a great fit if you’re using or building an FSE-compatible theme and want more control over your content structure—no conflicts, no hassle.
