A side-by-side comparison of Astryx and Justblank — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
A
Astryx
Meta
Meta's open-source React design system with 150+ accessible components, built for developers and AI assistants to build with the same tooling.
Key features
- 150+ Accessible Components: A cohesive React component library covering forms, navigation, data display, feedback, and more, all built for accessibility.
- Agent-Ready CLI: A scriptable CLI (`astryx component list`, docs, scaffolding, codemods) that Cursor, Claude Code, and Codex can drive directly.
- Swizzle for Full Ownership: Eject a component's full source into your project when you need to customize beyond props — no forking the library.
- Theme via CSS Variables: Themes are CSS custom-property overrides, so designers can rebrand Astryx without wrapping or forking component source.
- No Styling Lock-In: Styles are authored with StyleX internally but you override with Tailwind, CSS modules, or plain CSS — no library adoption required.
- Seven Ready-Made Themes: neutral, butter, chocolate, matcha, stone, gothic, and y2k themes ship out of the box and are fully customizable.
- Dark Mode + Brand Theming: Brand-level theming and dark mode work together across every component without extra wrapping.
- Live Docs, Storybook & Sandbox: Full docs at astryx.atmeta.com, a hosted Storybook, and an interactive Sandbox for humans and agents to explore.
Best for
- AI-Assisted UI Builds: Let an agent scaffold a React app that a designer and engineer both extend, all from the same component and CLI reference.
- Rapid Product Prototyping: Assemble accessible screens from ready-to-ship templates and swap themes to prototype multiple brand directions.
- Design System Adoption: Replace a hand-rolled component library with a maintained, accessibility-audited system without changing your styling approach.
- Rebrand Without Forking: Ship a distinct visual identity by overriding CSS custom properties instead of forking the component source.
- Multi-Framework Codebases: Bring Astryx into a project that already uses Tailwind, CSS modules, or plain CSS without adopting a new styling library.
- Component-Level Customization: Use swizzle to eject specific components when you need internal control while keeping the rest of the system managed.
