Chrome Extensions for React Developers (1970)
Essential browser extensions to debug components, inspect styles, analyze performance, and speed up your React development workflow.
Skip the Extension Bloat
Instead of installing 5+ separate extensions for CSS inspection, color picking, font detection, and screenshots, Frontend Hero bundles 11 developer tools into one. Works perfectly with React, Next.js, and all modern frameworks.
Get Frontend HeroReact Debugging
React Developer Tools
The official React debugging extension from Meta. Inspect the React component tree, view props and state, and trace component updates.
Why React devs love it: Essential for any React project. Debug component hierarchies, track state changes, and identify unnecessary re-renders.
State Management
Redux DevTools
Debug Redux state changes with time-travel debugging. View action history, inspect state at any point, and replay actions.
Why React devs love it: If you use Redux, RTK, or Zustand with Redux DevTools integration, this is indispensable for debugging complex state flows.
All-in-One Developer Toolkit
Frontend Hero11-in-1
11 developer tools in one extension: CSS Scanner, Color Picker, Font Explorer, Element Screenshot, Tailwind Scanner, Page Ruler, Asset Spy, and more.
Why React devs love it: Inspect CSS on React components (including hover states), extract colors with Tailwind class output, identify fonts, and capture component screenshots. Works perfectly on localhost and Next.js dev servers.
API Development
JSON Viewer
Formats JSON responses in the browser with syntax highlighting, collapsible trees, and search functionality.
Why React devs love it: When debugging API responses or checking your REST/GraphQL endpoints, readable JSON makes a huge difference.
Technology Detection
Wappalyzer
Identify technologies used on any website including frameworks, libraries, CMS, and hosting providers.
Why React devs love it: See how other sites implement React (Next.js vs Gatsby vs Vite), what UI libraries they use, and learn from production implementations.
Performance
Lighthouse
Google's tool for auditing performance, accessibility, SEO, and best practices. Built into Chrome but the extension provides quicker access.
Why React devs love it: Catch performance issues in your React app: bundle size problems, render-blocking resources, accessibility issues, and Core Web Vitals.
Design
Eye Dropper
Simple, reliable color picker that works on any webpage. Open source and privacy-focused.
Why React devs love it: Quickly grab colors from designs or competitor sites when styling your React components.
WhatFont
Hover over any text to identify the font family, size, weight, and line-height.
Why React devs love it: Match typography from designs or identify fonts on sites you're recreating in React.
Responsive Testing
Window Resizer
Quickly resize your browser to test responsive breakpoints. Preset sizes for common devices.
Why React devs love it: Test your React components at different viewport sizes without manually dragging the browser window.
Screenshots
GoFullPage
Capture full-page screenshots with one click. Handles infinite scroll and lazy-loaded content.
Why React devs love it: Document your React app for PRs, bug reports, or client presentations. Captures the entire page, not just the viewport.

Frequently Asked Questions
React DevTools has minimal performance impact when not actively in use. The profiler does add some overhead when recording, but it's negligible during normal development. You can disable it on production sites if concerned.
React Developer Tools works with all React-based frameworks including Next.js, Remix, Gatsby, and Vite. Frontend Hero is specifically tested to work on localhost and Next.js dev servers where some other extensions fail.
You can use individual free extensions (Eye Dropper for colors, WhatFont for fonts, etc.), but Frontend Hero bundles all of these plus 8 more tools into one extension. It's more convenient and avoids extension bloat.
TanStack Query has its own DevTools that integrate directly into your app rather than as a browser extension. You add it as a component in development mode. It works alongside these browser extensions.
