Content Blocks Builder – Create blocks, repeater blocks with carousel, grid, popup layouts for WordPress Plugin Directory

Content Blocks Builder (CBB) helps you create custom blocks, variations, styles, and patterns — directly in the Block Editor without touching a code editor.

The WordPress Block Editor (Gutenberg) is a solid foundation for building websites. But when you need more specific layouts or custom functionality not available in default blocks, you’re often forced to write custom code or rely on bloated third-party plugins.

CBB solves this by letting you visually group core or third-party blocks into flexible container blocks — right inside the native Block Editor. These container blocks support native features like typography, spacing, colors, borders, plus advanced features from CBB that help you build layouts like responsive grid, slider/carousel, toggle/accordion, modal/off-canvas/popover, background effects all without writing a single line of code.

You can also build repeater blocks to display repeatable content — similar to ACF repeater field type, but entirely block-based and visual.

👉 Read the detailed guide to CBB blocks.

The ultimate goal of CBB is to help you build complex layouts — all with core blocks, all visually, and fully compatible with any Gutenberg-ready theme.

No React. No PHP. No lock-in. No clutter. No bloat. Developer-friendly.
