Is NexaBlocks really free?
Yes. The core plugin with 20+ blocks is free forever on the WordPress.org plugin directory. Pro and Agency add premium blocks, templates and priority support.
Will my site slow down?
No. NexaBlocks loads only the CSS and JavaScript needed by the blocks actually used on the page (tree-shaken at runtime). The free plugin adds about 14KB of CSS and 6KB of JS to a page that uses every block.
Do you support full-site editing (FSE)?
Yes — every block ships native to Gutenberg and can be used in templates, template parts and patterns inside the Site Editor.
Which themes does it work with?
Any block-aware WordPress theme. We test against the default Twenty Twenty-Four / Twenty Twenty-Five themes and our own Nextra theme.
