Meta released the Astryx design system — an open-source React library engineered from the ground up for seamless collaboration between engineers and AI agents through a unified API and a built-in MCP server.
What is Astryx?
Astryx is Meta's open-source React design system built on top of StyleX, which compiles styles into atomic CSS at build time. Theming works through design tokens (CSS variables) that can be overridden at any level of the component tree. It ships with a CLI and an MCP server, so AI agents like Claude or GPT work with the same components, commands, and documentation as human engineers. The project evolved inside Meta for eight years and is currently in Beta.
Is Astryx free for commercial use?
Yes — Astryx is available under the MIT license with no restrictions on commercial use.
