AI-agent-driven design-to-code canvas for product teams wanting designers, engineers and coding agents shipping the same live prototype.
What it does
Prototyper is a visual canvas where design changes and code stay in sync in real time, letting designers, engineers and AI coding agents (like Claude Code, Codex or Cursor) work on the same running prototype. Agents can read a project's files, write React code, and open pull requests directly from the canvas, which also connects to tools like GitHub, Google Drive, Linear and Notion.
Core features
Live two-way sync between visual canvas and real code
Multiplayer support for humans and AI agents together
Bring-your-own-agent support (Claude Code, Codex, Cursor, Copilot)
MCP integration for GitHub, Drive and other tools
Component/design token system for on-brand output
Shareable running previews instead of static mockups
Best for
→Product teams prototyping UI with AI agents doing the coding
→Designers and engineers collaborating on one shared artifact
→Reviewing a live running prototype instead of static mockups
→Directing multiple coding agents in parallel on one project
