Refine UI in the browser, feed changes to your coding agent
Handle Extension is an innovative browser-based tool designed for developers and UI designers seeking a more direct and efficient way to refine user interfaces. Unlike traditional methods that involve endless re-prompting or editing code through external environments, this extension allows users to point and fix UI elements directly within the browser. It seamlessly integrates with popular AI coding agents like Claude Code, Codex, and Cursor, enabling real-time, visual adjustments that are instantly communicated to your coding environment. This approach significantly accelerates the UI iteration process, making it ideal for rapid prototyping, bug fixing, or minor tweaks without switching contexts. Its open-source nature and compatibility with Chrome further enhance its appeal, fostering community-driven improvements and adaptability for various workflows. Handle Extension empowers developers and designers to streamline their UI refinement workflow, saving time and reducing frustration while maintaining high precision and control.
