What it solves

It simplifies the process of providing AI agents with the exact source code context of a UI element. Instead of manually searching through files to find where a component is defined, developers can quickly capture the precise location of a UI element to help an agent modify or understand it.

How it works

React Grab integrates into a development environment and allows a user to hover over any UI element in the browser and copy it using a keyboard shortcut (Cmd+C or Ctrl+C). The tool then captures the selected element's HTML and its component stack, including the specific file path and line number where the code resides.

Who it’s for

Frontend developers who use AI agents to build or maintain React-based applications.

Highlights

• Source Mapping: Provides the exact file and line number for the selected UI element.
• Fast Integration: Can be initialized via a CLI command or manually added to Next.js (App and Pages routers), Vite, or Webpack.
• Extensible: Includes a primitives library for building custom selection interfaces with APIs for hit testing and page freezing.
• Performance: Claims to make agents 2x faster and more accurate by providing direct source context.
