Meta's Astryx is an open-source React design system built on StyleX, currently in beta under MIT license, developed internally at Meta for over eight years. It uniquely combines CSS variable theming with a command-line interface (CLI) and Model Context Protocol (MCP) server, allowing both human engineers and AI agents to use the same API for UI construction. This provides AI builders with a practical example of seamlessly integrating AI agents into existing frontend workflows.
