However, you can use the shortcodes within any page builder (Elementor, DIVI, Beaver Builder, Visual Composer, Oxygen, etc.) to design your own custom pages. It has better integration with Elementor so you can design visually within Elementor editor. For more details, you can check out the documentation on how to use BetterDocs Shortcodes.
BetterDocs comes with ready blocks, docs category archive page layouts, and a lot of different elements for Elementor page builder. You can use any of these ready designs or elements to easily add BetterDocs inside your Elementor pages and style them any way you want.
