Core Framework

Core Framework is a free, open-source tool for building and managing design systems visually. It generates portable CSS frameworks with design tokens, utility classes, and components that work across the web, WordPress, Gutenberg, Bricks, Oxygen, and Figma. Users can customize colors, typography scales, spacing, and components through a visual editor, then export organized stylesheets or download as a portable project file.

The framework emphasizes consistency and team collaboration by providing a visual source of truth for design systems. It includes a component editor for creating reusable UI elements, smart color system generation, and modular architecture that lets teams add, remove, or customize any part. All integrations are included in a single free plugin with no license keys or paid feature gates.
