No single extension is established as a universal winner. Check the current Chrome Web Store listing, publisher, permissions, and compatibility before installing.
Choose an extension for the task you need to do
Extensions can add specialized views or actions to Chrome, but they are not automatically better than browser features you already have. Start with the task, then decide whether an extension fills a real gap.
| Task | Extension to consider | What the available listing says |
|---|---|---|
| Inspect or profile a React app | React Developer Tools | Adds Components and Profiler tabs to Chrome DevTools, where developers can inspect the component hierarchy and view or edit current props and state. Chrome Web Store |
| 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. Chrome Web Store |
| Identify a site’s technology | BuiltWith Technology Profiler | The developer category lists it for website technology identification. Chrome Web Store |
| Intercept or modify HTTP(S) requests | Requestly | The category lists it for HTTP(S) request interception and modification. Chrome Web Store |
| Format or analyze JSON | JSON Viewer Pro | The category lists it for JSON formatting and analysis. Chrome Web Store |
| Pick a color from a page | Eye Dropper | The category lists it as a color-picking tool. Chrome Web Store |
| Use a general developer toolbar | Web Developer | The category describes it as a toolbar of developer tools. Chrome Web Store |
| Debug or profile an Angular app | Angular DevTools | The category lists it for Angular-specific debugging and profiling. Chrome Web Store |
These descriptions identify intended use, not a comparative quality ranking. Verify the exact current listing and publisher before you install; names and listings can change.
React debugging: React Developer Tools
For a React application, React Developer Tools is the focused choice in this shortlist. Its Chrome Web Store listing says it adds Components and Profiler tabs to Chrome DevTools. Use the Components view to inspect the component hierarchy and view or edit current props and state; use the Profiler view when you need to examine application profiling information.

It is a React-specific aid, not a general-purpose page inspector. For non-React pages or browser-level debugging, use the relevant Chrome DevTools panels instead.
Automated audits: Lighthouse
Lighthouse is presented in the Chrome Web Store developer category as an open-source automated tool for improving web application performance, quality, and correctness. It can provide an audit starting point, but an automated report is not a substitute for manual diagnosis or broader testing of the page and its user journeys.

Should you install a separate Lighthouse extension?
The available listing information establishes Lighthouse as an audit tool, but does not establish current feature parity between a separate Lighthouse extension and the Lighthouse capability available through Chrome DevTools. Check current official documentation and the live listing for the version and workflow you intend to use; do not assume the two are interchangeable.
Other focused tools worth evaluating

Accessibility checks: treat extensions as complements
axe DevTools and WAVE appear in accessibility-tool roundups as options to evaluate. The official details for their individual listings are not established here, so confirm current features, publisher identity, permissions, and compatibility on each live listing before choosing one. An extension-based check should complement—not stand in for—accessibility testing of the actual interface and user flows.
How to choose and install safely
- Define the task. Decide whether you need framework inspection, an audit, accessibility checks, technology identification, request testing, color sampling, or JSON readability.
- Check built-in DevTools first. If Chrome already supports the job you need, an additional extension may not be necessary.
- Open the current Chrome Web Store listing. Confirm the exact name, publisher or developer identity, stated purpose, and compatibility information rather than relying on a search snippet or an old recommendation.
- Review permissions and site access. Install only if the requested access makes sense for the task and the sites where you plan to use it.
- Reassess periodically. Listings, permissions, compatibility, ratings, and pricing can change; verify current details when you install or revisit a tool.
Screenshot a page without adding a browser extension
If your developer task is capturing a website as an image or PDF, ScreenshotNeo is an alternative to try first: its API returns a screenshot or PDF from one GET request, and only clean shots are billed. It also offers an MCP server for AI agents. See ScreenshotNeo and its API documentation.
Or skip the browser setup
Send a URL to the API and save the returned image. Replace the URL as needed:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpScreenshotNeo accepts cookie or consent banners before capture and removes 60+ known consent platforms, newsletter popups, and chat widgets; each step can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits cost nothing, and response headers indicate the page verdict and billing. AI agents can use its MCP server. The free plan includes 1,000 shots per month with no card; paid plans start at $5 for 3,000 shots.
Sign up for 1,000 free screenshots a month—no card required.
