React Grab is a browser integration tool that extracts React component source context from UI selections for use by AI agents.
The tool solves the problem of agents lacking accurate source information when working with React applications. It works by allowing developers to hover over any UI element, press a keyboard shortcut to copy, and paste the resulting context into an agent. The copied context includes the selected element along with its full component stack and source file locations, enabling agents to understand the actual code structure behind what they see on screen.
Developers building AI-assisted coding workflows should consider React Grab if they want to improve agent accuracy and speed when modifying React applications. The tool supports multiple build setups including Next.js with both app and pages routers, Vite, and Webpack, with a CLI installer for quick setup or manual installation options. For teams needing custom behavior, the tool exposes a primitives API that allows building custom selection interfaces with hit testing, source context extraction, page freezing, clipboard access, and editor navigation capabilities.
The project maintains an active community presence with a Discord channel for discussion and contribution, a documented contributing guide, and a code of conduct. The maintainers actively triage bug reports and accept pull requests through the issue tracker. The tool includes a demo site and benchmarks showing performance comparisons, indicating ongoing investment in demonstrating its value to potential users.
