Show HN: Page.json – An open standard for representing UI (wuwei.us)

Page.json has been introduced as an open standard aimed at representing user interfaces (UIs) as data, encapsulating their content, layout, and interactions in a standardized format. This initiative parallels the MCP standard that governs how agents interact with tools, allowing for a more cohesive approach across various applications and platforms. By decoupling UIs from model providers, Page.json enables developers to create and manage interfaces independently, streamlining the integration of generative AI in UI development. The technical foundation of Page.json is a JSON tree structure, where each node represents a component with its associated content and layout. This versatile format not only allows for easy rendering across different mediums—such as web pages, mobile views, and rich text articles—but also encourages both human and AI interaction through any editing tool. As a result, Page.json transforms UIs into reusable digital artifacts, enhancing their accessibility and adaptability while promoting a more collaborative development environment within the AI/ML community. The full specification is available on GitHub for those interested in exploring its capabilities further.
