GitHub open-sources Replica, an AI prototyping tool built on your design system
round · x · 2026-10-29
GitHub open-sourced Replica, an AI-powered prototyping tool from GitHub Design that turns ideas into interactive prototypes using your own design system.
Key points:
- Unlike generic AI prototyping tools, it is guided by your team's existing components, patterns and documentation; designers define the guidance, anyone can create and refine prototypes in natural language inside the GitHub Copilot app
- Prototypes can be published to an optional self-hosted Replica Hub for teammates to explore and comment
- Fully open source and customizable to your workflows
The goal: help designers, PMs and engineers get feedback earlier and validate assumptions without starting from scratch.
