React Grab

Overview

React Grab is an innovative developer tool that enables users to select code context for AI coding assistants directly from their browser. With simple keyboard shortcuts, developers can capture file names, React component information, and HTML source code for any UI element, providing precise context information to AI assistants.

The tool offers a visual interface that lets developers point at any UI element in their browser and automatically extract relevant code information. Tests show that using React Grab can make AI coding tools like Cursor, Claude Code, and GitHub Copilot run up to 3x faster while significantly improving accuracy.

Key Features

• One-Click Context Copy: Simply point at any element and press ⌘C (Mac) or Ctrl+C (Windows/Linux) to copy file name, React component, and HTML source code
• Cross-Framework Support: Works with Next.js (App Router & Pages Router), Vite, Webpack, and other major React build tools
• Plugin System: Rich plugin API supporting custom context menu actions, toolbar menu items, lifecycle hooks, and theme overrides
• MCP Integration: Quickly integrate into the Model Context Protocol (MCP) ecosystem via command line
• Visual Highlighting: Real-time element highlighting on hover for intuitive selection experience
• Development-Mode Only: Only loads in development mode, with zero impact on production performance
• Primitives API: Build custom element selectors from scratch using standalone utility functions

Use Cases

• AI-Assisted Programming: Provide precise UI element context to Cursor, Claude Code, Copilot, and other AI coding assistants
• Code Review & Debugging: Quickly locate and review source code locations for specific UI elements
• Team Collaboration: Rapidly share code information for UI elements with team members to improve communication
• Learning React Structure: Visually learn and understand component hierarchies in existing React applications
• Automated Testing: Assist in locating and selecting UI elements that need testing
