Replica
GitHub Design's MIT-licensed AI prototyping tool that builds interactive prototypes from your own design-system components via Copilot.
Overview
GitHub Design released Replica on October 28, 2026 as open-source tooling for turning an idea described in natural language into an interactive prototype through the GitHub Copilot app. Prototypes are guided by a team's own components, patterns and documentation. Teams can prototype locally or publish to an optional self-hosted Replica Hub, where teammates can explore and comment. The code is MIT-licensed at github.com/github/replica and teams can adapt the tooling and guidance to their own workflows.
This is a sourced directory entry. Features and capabilities are reported in the linked sources; this entry does not document independent Aymorphic testing.
