Stackable Premium is a plugin for the WordPress block editor (Gutenberg) that expands its functionalities. It essentially turns Gutenberg into a more powerful page builder.

With Stackable Premium, you get additional block types for things like galleries, accordions, and fancier buttons. You can also customize these blocks more extensively and create unique layouts for your website. It’s a good fit for users who want more design control over their WordPress sites without needing to code.
