About Handle

Handle is a free and open-source AI coding workflow tool that enables users to refine user interfaces directly in production code. It provides a Chrome extension and a macOS app that allow designers and engineers to visually select elements, adjust styles and layout, and then send precise feedback to a range of AI coding agents, including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Rovo Dev, and Windsurf. The tool aims to eliminate handoff gaps and reduce iteration cycles by making changes that flow directly into the codebase, bypassing the need for tickets, mockups, or repeated prompting.

Handle operates in two modes: a Chrome extension for lightweight adjustments during live development, and a desktop Studio app for more comprehensive design refinement. Both modes integrate with the user's existing coding agent and local development server. Users invoke the tool with a /handle command to capture UI context and land changes in code. The platform emphasizes 'less translation, more intention' by allowing direct manipulation of live UI elements.

As an open-source tool, Handle requires no account to download or use, and users bring their own agents. It is designed for design engineers and product designers working on web applications, providing real-time previews and precise control over styling and behavior. The tool supports a variety of coding agents, making it flexible for different workflows.
