What is uistudio.dev?

uistudio.dev is a browser extension that transforms any React site into a visual code editor. It lets you edit interfaces directly in the browser in real-time, then send structured context to coding agents like Cursor, Claude Code, or VS Code. The result is production-ready code that reflects your visual changes instantly.

Who it's for

• Frontend developers who want to iterate on UI designs directly in the browser without switching between tools.
• Design engineers who need to pull design tokens and assets from inspiration sites and repurpose them into code blocks.
• Indie founders who ship fast and want a visual bridge between their browser and their coding agent for rapid prototyping.

Key features

Real-time visual editing

Edit any React interface directly in your browser. Changes appear instantly on the live page, so you see exactly what the final result will look like without reloading or rebuilding.

IDE bridge integration

Send structured context from your browser to Cursor, Claude Code, or any coding agent running locally. The extension acts as a visual bridge, translating on-screen edits into actionable code instructions for your IDE.

Asset and token extraction

Pull design tokens, colors, spacing, and assets from any inspiration site. Repurpose them into code blocks or structured context that your coding agent can use immediately.

Production-ready output

The code generated from your visual edits is clean and ready to ship. No messy prototypes — just production-quality React code that you can drop directly into your project.

What stands out

"UiToolbar is the visual bridge that connects your browser to your coding agent."

This one-liner captures the product's core edge: it doesn't replace your IDE or agent — it makes them work together seamlessly. Instead of describing UI changes in text or switching between tools, you edit visually and let the extension translate your work into structured context for your coding agent. This eliminates the friction of manual handoffs and keeps you in a fast, visual feedback loop.

Worth checking out if…

You build with React and want to speed up your UI iteration cycle. If you already use Cursor, Claude Code, or VS Code with a coding agent, uistudio.dev gives you a visual layer on top — so you can edit live interfaces and push structured context directly to your agent. It's especially useful for frontend developers, design engineers, and founders who ship frequently and want to reduce context switching.
