Handle

Edit live web interfaces with visual tools connected to your code

Meet Handle

Handle gives designers and developers visual tools for changing live web interfaces and bringing those changes into production code. Users select elements, refine styling and layout, and work with their existing coding agent to apply the result. The workflow supports exploring an interface, adjusting it against a design system, and reviewing changes in a live preview.

It is available as a Chrome extension and a macOS application called Handle Studio. The extension connects to an existing development server and supports several coding agents. Studio provides a dedicated workspace for deeper design work. Both are presented as free and open source, with Studio available without an account.
