Catalog is an open-source tool for building living style guides that combine design documentation with real, interactive components. Tailored for digital product teams, it offers a central space to document UI patterns, design tokens, and developer-ready components—bridging the gap between design and engineering. Users can install and launch a local Catalog environment with a few CLI commands, where they can write Markdown files, embed React components, and preview them live alongside documentation.
The system is especially useful for teams looking to standardize their design system implementation while maintaining developer flexibility. Catalog supports version control, customization, and seamless integration with GitHub, enabling teams to document their component libraries in real-time. It helps ensure design consistency, improves collaboration across disciplines, and supports continuous iteration as products evolve.
