Overview

Product summary

Review the store description, core capabilities, and common use cases.

Lighthouse is an open-source, automated tool for improving the performance, quality, and correctness of your web apps.

When auditing a page, Lighthouse runs a barrage of tests against the page, and then generates a report on how well the page did. From here you can use the failing tests as indicators on what you can do to improve your app.

Web page performance and quality auditing tool that generates Lighthouse reports

Helps developers identify performance bottlenecks, accessibility issues, SEO problems, and best-practice violations on web pages

User clicks the extension icon, selects preferred settings (backend, device, categories, locale), then clicks 'Generate report'. The extension opens an external web tool (pagespeed.web.dev or googlechrome.github.io/lighthouse/viewer/) with the current tab's URL and settings as query parameters, where the Lighthouse analysis runs and displays the report.

Target users: Web developers / Frontend engineers / Web performance engineers / SEO professionals / Accessibility specialists

The extension is a thin launcher — the actual Lighthouse analysis runs on external web services (pagespeed.web.dev or Lighthouse Viewer), not within the extension itself. The destination services are free Google tools with no login required for basic use.

Monetization

No paid features detected

The extension is open-source (Apache-2.0 license) with no payment UI, no billing code, no premium feature gating, and no subscription logic. All four audit categories (Performance, Accessibility, Best Practices, SEO) are available to all users. Keyword hits for 'pro' and 'license' are false positives: 'pro' appears in CSS comments about 'property name' and 'protocol', while 'license' refers to SPDX license identifiers.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login UI or authentication flow. It simply reads the current tab URL via chrome.tabs.query and opens an external web tool (pagespeed.web.dev or googlechrome.github.io/lighthouse/viewer/) with the URL as a query parameter. Settings are persisted locally via chrome.storage.local with no account association.
