## Best for

Product teams that want AI-generated prototypes to follow their real components and guidance instead of a generic component kit.

## Why it deserves attention

Replica, released by GitHub Design under the MIT license, lets designers encode their components, patterns, and documentation as guidance, then lets anyone on the team describe a screen in natural language inside the GitHub Copilot app and refine the running prototype beside the conversation. It runs locally without a server, and an optional self-hosted Replica Hub adds publishing and comments for review. It works on macOS and Linux with Git and Node, and the canvas requires the Copilot app and GitHub sign-in, using GitHub-hosted models or your own provider. It is early and small: the workflow is tied to Copilot, the hosted Hub needs DNS, HTTPS, and server setup, and output is a prototype rather than production code.
