About
A React-based tool or utility for grabbing and extracting content or data from web sources. Designed to simplify data collection processes for developers working with React applications.
What it does
React Grab lets you point at a rendered interface element and copy useful source context for an AI coding agent. The copied text combines the element markup, its React component stack, and source locations, giving the agent a direct trail from the browser view back to the implementation.
Why it's ranked here
This solves a narrow but costly communication problem: identifying exactly which code produced a visible element. The hover, copy, paste loop is easy to understand, while the component stack and source coordinates provide more precision than screenshots or verbal descriptions. A customizable selection engine makes it useful beyond the default interface.
What's good
Setup covers Next.js, Vite, and Webpack, with development-only loading shown for each. The public selection engine exposes hit testing, source context, page freezing, clipboard access, and editor navigation. Custom filters can restrict selectable elements, and an ignore marker prevents tool controls from selecting themselves.
Tradeoffs
React Grab supplies context to an agent, but it does not perform edits or replace the agent itself. Its core value depends on source locations being available and useful. Manual installation varies by framework, while the quickest setup requires a command-line initializer. The browser workflow also adds a copy-and-paste step to each request.
How to use it well
Use it when developers or designers can reproduce a UI issue locally but struggle to name the responsible component. Install it only for development, select the smallest relevant element, then paste the resulting context beside a clear change request. Choose another tool for crawling external sites, collecting general web data, or executing code changes.
Technical notes+
The root package.json defines a private pnpm workspace monorepo with apps/* and packages/*, Turbo tasks, Node 22 or newer, and TypeScript tooling. packages/cli/src/cli.ts exposes init, add, remove, configure, upgrade, pull, stop, and a hidden watch command; when telemetry is enabled it attempts a version request. packages/react-grab/src/index.ts auto-initializes a browser global unless disabled and exports the main API, plugins, errors, types, and global registration helpers. packages/react-grab/vite.config.ts emits a browser IIFE plus CJS and ESM modules with declarations, including separate core and primitives entries. The implementation in packages/react-grab/src/core/index.tsx uses Solid.js internally. packages/react-grab/playwright.config.ts defines Chrome-based development, production, touch, performance, and coverage runs across Vite, Next.js, and TanStack Start fixtures.
