Astrum is a lightweight, developer-friendly pattern library designed for teams building design systems and component libraries for the web. Built by NoDivide Studio, it enables designers and developers to collaboratively document UI patterns without complex tooling or heavy dependencies. With a minimal setup, Astrum supports Markdown-based documentation and easy embedding of code examples, making it an ideal choice for design teams who want to maintain a style guide alongside a working component library.
Unlike larger tools like Storybook or Pattern Lab, Astrum focuses on simplicity and speed. It doesn’t require a JavaScript framework and is completely static by default—making it well-suited for static sites, rapid prototyping, or design system documentation embedded into any codebase. Astrum’s CLI allows you to scaffold new components, manage files, and render a customizable UI with clean, focused documentation for each element.
Whether you’re documenting a product’s UI tokens, components, or patterns, Astrum strikes a balance between structure and flexibility. It’s great for smaller teams or solo developers looking for a zero-bloat solution to visually organize front-end building blocks. The clean interface and version-controlled Markdown approach make it ideal for teams who prioritize clarity, accessibility, and portability in their documentation workflow.
