Meta's open-source React design system with 150+ accessible components, built for developers and AI assistants to build with the same tooling.
Astryx is an open-source design system Meta grew internally over eight years — the most-used and largest design system in the company, powering 13,000+ apps — now released for public use. It ships 150+ accessible React components, brand-level theming, dark mode, ready-to-ship templates, and a CLI as one cohesive system, so you import pre-built CSS and use typed React components without adopting a styling library or configuring a build plugin. What makes Astryx different is that the API, docs, and CLI are designed for both humans and AI coding assistants to build the same way, from the same reference — the CLI is scriptable enough that agents in Cursor, Claude Code, or Codex can query component docs and scaffold themes directly. Components are built to be composed at any level with a `swizzle` command that ejects a component's full source into your project, styling can be overridden with Tailwind or plain CSS, and themes are just CSS custom-property overrides so no fork or wrapper is needed.
Astryx is Meta's open-source React design system featuring over 150 accessible components. It is designed specifically for developers and AI assistants, allowing them to utilize the same tools and resources, thereby streamlining the development process and enhancing user experience across applications.
Astryx serves as a robust foundation for building user interfaces in React applications. This design system includes pre-built components like buttons, forms, and navigation elements that adhere to best practices in accessibility and usability. Here are key features that make Astryx stand out:
Component Library: With more than 150 components, developers can quickly assemble applications without starting from scratch. These components are customizable, allowing for consistent branding across projects.
Accessibility Compliance: Every component in Astryx is designed to meet major accessibility standards, such as WCAG (Web Content Accessibility Guidelines). This focus on accessibility ensures that applications are usable by everyone, including those with disabilities.
Developer and AI Assistant Friendly: Astryx is optimized for collaboration between human developers and AI tools. By using the same design system, developers can create applications that leverage AI capabilities, such as smart recommendations or automated workflows.
Responsive and Mobile-First Design: The components are built with responsiveness in mind, enabling applications to function smoothly across various devices, which is crucial in today’s mobile-centric world.
Astryx works by integrating over 150 accessible React components, a scriptable CLI for automation, and customizable themes through CSS variables. It enables seamless AI-assisted UI builds and rapid prototyping, allowing designers and engineers to collaborate efficiently without the need for forking the component library.
Astryx is designed to streamline UI development by providing a comprehensive library of accessible React components. This library includes essential UI elements such as forms, navigation, and data displays, ensuring that users can create engaging interfaces while adhering to accessibility standards.
The Agent-Ready CLI allows developers to utilize commands like astryx component list, which lists available components, and provides scaffolding tools to initiate projects quickly. This CLI can be integrated with AI tools like Cursor, Claude Code, and Codex, enabling automated scripting and enhancing productivity.
One of the standout features is Swizzle, which allows developers full ownership of component source code. When a component needs customization beyond props, you can eject its source directly into your project, eliminating the need for forking the original library. This feature fosters innovation while maintaining a clean codebase.
Astryx also supports theming via CSS variables, enabling designers to easily rebrand components without modifying the source code. By overriding CSS custom properties, teams can create distinct visual identities while using the same underlying component framework.
Moreover, Astryx promotes no styling lock-in. Styles are authored using StyleX, but developers can override these styles with Tailwind, CSS modules, or plain CSS. This flexibility allows teams to integrate Astryx into existing projects without needing to adopt a new styling library.
Astryx features over 150 accessible components, an agent-ready CLI, the ability to customize components easily, CSS variable theming, and flexible styling options. These features make Astryx an excellent choice for developers seeking a robust, accessible, and customizable React component library.
Astryx stands out in the React ecosystem due to its extensive 150+ accessible components. These components encompass forms, navigation, data display, and feedback elements, all designed with accessibility in mind. This focus ensures that developers can create user-friendly applications that comply with accessibility standards, making it an ideal choice for inclusive design.
The Agent-Ready CLI is another significant feature of Astryx. With commands like astryx component list, developers can easily access component documentation, scaffolding tools, and codemods. This CLI is designed to work seamlessly with AI tools like Cursor, Claude Code, and Codex, enabling developers to streamline their workflow and improve efficiency.
Customization is made easy with the Swizzle feature, which allows developers to eject a component's full source code into their project. This is particularly useful for developers who need to make extensive modifications beyond simple prop changes, eliminating the need to fork the library. This flexibility ensures that projects can maintain unique styling and functionality without compromising on maintainability.
Furthermore, Astryx supports theming through CSS variables, allowing designers to rebrand components effortlessly. This feature enables a high level of customization while retaining the core library's integrity. The absence of styling lock-in means developers can write styles using StyleX, Tailwind, CSS modules, or plain CSS without being tied to a specific library.
Astryx is designed for developers, designers, and teams interested in AI-Assisted UI Builds, rapid product prototyping, and seamless design system adoption. It benefits those looking to rebrand without forking code and integrates easily into multi-framework codebases, enhancing workflow efficiency and accessibility.
Astryx offers a suite of features tailored for various stakeholders in the development and design process.
AI-Assisted UI Builds: With Astryx, an intelligent agent can scaffold a React application, allowing designers and engineers to work collaboratively. For instance, a designer can prototype a user interface while the engineer focuses on functionality, all referencing the same components through a Command Line Interface (CLI).
Rapid Product Prototyping: Teams can leverage pre-built templates to assemble user-friendly screens quickly. By using Astryx, businesses can easily swap themes to explore different branding directions, enabling them to visualize multiple concepts within hours rather than weeks.
Design System Adoption: Organizations can replace outdated component libraries with a modern, maintained design system without sacrificing their existing styling approach. This transition not only enhances accessibility but also streamlines future updates and maintenance.
Rebrand Without Forking: Astryx allows teams to implement a new visual identity by overriding CSS custom properties rather than forking the source code. This approach minimizes technical debt and simplifies future updates.
Multi-Framework Codebases: Astryx is compatible with various styling methodologies, including Tailwind, CSS modules, and plain CSS. This flexibility makes it easy to integrate into existing projects, allowing teams to leverage its capabilities without a complete overhaul of their current setup.
By leveraging Astryx, teams can enhance their development and design processes, leading to efficient workflows and high-quality products in less time.
