What is Handle?
Handle is a specialized design-to-code tool that allows developers and designers to modify web applications directly within the production environment. Built to bridge the gap between visual design and actual implementation, it provides both a Chrome extension and a macOS desktop application called Studio. The tool integrates seamlessly with popular AI coding agents like Cursor, GitHub Copilot, and Claude Code to translate visual adjustments into real code changes. By working on live UI, users can eliminate the friction of traditional handoff processes and avoid the loss of context that occurs with static mocks. Handle is particularly effective for design engineers who want to iterate quickly on layouts and styling without leaving their development workflow. It empowers teams to land changes directly in their codebase, ensuring that what is designed is exactly what is shipped.
