Choose one for the job at hand: React Developer Tools for React inspection, Lighthouse for automated audits, or a focused utility for tasks such as identifying a site’s technology or modifying HTTP requests. Check the current Chrome Web Store listing, publisher, permissions, and compatibility before installing; the recommendations below are based on listing descriptions, not hands-on testing.
Choose an extension for the task you need to do
The useful distinction is not which extension wins overall, but which one supports your current workflow. The Chrome Web Store developer category lists tools for several different jobs; its descriptions establish their intended use, not a comparative ranking or independent quality assessment.
| Task | Extension to consider | What the listing says it does |
|---|---|---|
| Inspect or profile a React app | React Developer Tools | Adds Components and Profiler tabs to Chrome DevTools for examining a React component hierarchy and viewing or editing current props and state. |
| Run an automated quality audit | Lighthouse | Described by the Chrome Web Store developer category as an open-source automated tool for improving web app performance, quality, and correctness. |
| Identify a website’s technologies | BuiltWith Technology Profiler | Listed for website technology identification. |
| Intercept or modify requests | Requestly | Listed for HTTP(S) request interception and modification. |
| Format or analyze JSON | JSON Viewer Pro | Listed for JSON formatting and analysis. |
| Pick a color from a page | Eye Dropper | Listed for color picking. |
| Use a developer toolbar | Web Developer | Listed as a toolbar of developer tools. |
| Debug an Angular app | Angular DevTools | Listed for Angular-specific debugging and profiling. |
React Developer Tools: inspect React components
For React-specific debugging, React Developer Tools adds Components and Profiler tabs to Chrome DevTools. The Components panel lets you inspect the component hierarchy and view or edit current props and state. It is intended for React application work, rather than as a general-purpose inspector for every page.
Use it when the question is about how a React component is structured or what props and state it currently has. Verify that the live listing identifies the publisher you expect and supports your Chrome setup before installing.

Lighthouse: run an automated audit
The Chrome Web Store developer category describes Lighthouse as an open-source automated tool for improving the performance, quality, and correctness of web apps. It can be an audit option when you want automated findings, but an audit is not a substitute for manually diagnosing a problem or testing the broader experience.
Should you install a Lighthouse extension?
That depends on the workflow you want and what your current Chrome installation already provides. The available listing information supports describing Lighthouse as an audit tool, but it does not establish current feature parity between a separate Lighthouse extension and Lighthouse in Chrome DevTools. Check current official documentation and listings before choosing between them; do not assume one offers identical behavior or capabilities to the other.

These are task matches, not endorsements or evidence that one tool is better maintained or more capable than another.
Accessibility checks
axe DevTools and WAVE are names to evaluate if you want a dedicated accessibility checker alongside other audits. The available evidence does not verify the current details of their individual listings, so check each official listing for its present features, publisher, permissions, and compatibility rather than relying on a roundup description.

How to choose and install safely
- Define the job. Decide whether you need framework inspection, an automated audit, accessibility checks, technology identification, request testing, JSON readability, color selection, or a general toolbar.
- Check whether Chrome already covers it. Compare the extension’s purpose with the relevant built-in Chrome DevTools workflow. Avoid adding an extension when it does not provide a useful capability for your task.
- Verify the current listing. Confirm the extension name and publisher, read the permissions it requests, and check its compatibility and maintenance signals. Listings, permissions, ratings, and availability can change.
- Install only what you need. Prefer a focused tool for a specific job, then review whether it behaves as expected in your development workflow. No extension in this guide was independently installed or tested.
