Quey vs React Grab

Quey vs React Grab: a browser extension vs a package you add to your app.

React Grab and Quey solve a similar problem — turning a clicked UI element into context a coding agent can act on. The main difference is where they run: React Grab is installed as a dependency inside your React app, while Quey is a Chrome extension that works on any page without touching your codebase, plus adds visual style editing on top of capture.

FeatureQueyReact Grab
What it isChrome extension for visual capture and agent handoffOpen-source npm package for selecting DOM elements and copying agent context
Where it runsAny webpage, via a browser extension — no app changesInstalled inside your React app as a dependency

Hands context to your coding agentYes — MCP bridge and structured clipboard payloadYes — copies element and source context, includes an MCP server
Design values capturedColors, fonts, radius, spacing, and layoutSelector, source file, and component tree
Visual style editingYes — Frame/Font/Color tools with a live previewNo — capture and handoff only
Framework requirementWorks on any page Chrome can render; source hints are richest with framework metadataBuilt specifically for React apps

When to use each

Neither tool is wrong — they fit different moments.

Reach for Quey when

  • You don't want to add another dependency to the app you're inspecting
  • You want to change colors, fonts, or spacing visually, not just capture a selector
  • You want the same tool to work across projects without installing it into each one

Reach for React Grab when

  • You're already deep in a React codebase and want a package-level integration
  • You want an open-source, self-hosted option with no extension install
  • You need its broader MCP browser-automation surface (navigate, click, fill forms)

FAQ

Common questions

Is Quey a fork of or based on React Grab?

No, they're independent projects. Both address the same broad problem — getting a coding agent real context from a clicked UI element — but Quey runs as a browser extension rather than an in-app package, and adds visual style editing.

Do I need to install anything in my app to use Quey?

No. Quey runs entirely as a Chrome extension. The optional local MCP bridge runs as a CLI process in your project directory — it isn't a dependency added to your app's code.

Does Quey work on non-React apps?

Yes. Quey captures the DOM, computed styles, and design values on any page. Source-file hints (component name, file path, line number) are most precise on frameworks that expose that metadata, but the core capture works everywhere.
