Hushbug vs Lighthouse
Lighthouse audits a single page on demand. Hushbug monitors every page you visit in real time. See when each tool is the right choice.
Short answer: Lighthouse audits one page at a time when you ask it to. Hushbug monitors every page you visit as you work. They catch different things at different times.
What Lighthouse does
Lighthouse is Google's open-source auditing tool, built into Chrome DevTools. You open DevTools, click "Lighthouse," pick your categories (Performance, Accessibility, Best Practices, SEO, PWA), and hit "Analyze page load." It loads the page in a simulated environment, runs ~150 audits, and produces a report with scores and recommendations.
The reports are thorough. Performance gets broken down into FCP, LCP, TBT, CLS, and Speed Index. Accessibility runs axe-core checks. Best Practices catches HTTPS issues, deprecated APIs, and console errors present at load time. It is the standard tool for "how does this page perform and what should I fix?"
Lighthouse is free, always available in DevTools, and well-documented. You can also run it from the command line (npx lighthouse) or through PageSpeed Insights for field data.
What Hushbug does differently
Hushbug runs in the background while you browse. You do not trigger it manually per page. As you navigate your app, click buttons, fill out forms, and test flows, Hushbug catches issues as they happen. A layout shift during a state change, a 404 when a user clicks a broken link, a console error after an interaction. These are runtime issues that a page-load audit will not see.
Lighthouse simulates a single page load. Hushbug watches ongoing behavior across all tabs. A form submission that triggers a CORS error, a lazy-loaded component that throws a TypeError, a fetch request that takes 8 seconds after the user scrolls. Lighthouse would miss all of these because they happen after the initial load audit is complete.
The coverage is also different. Lighthouse gives you a deep audit of one page. Hushbug gives you surface-level monitoring across every page you visit during a development session. You see all the errors from your entire workflow, not a detailed report for a single URL.

| Network failure detection | No | Yes (failed fetch/XHR, slow requests) |
| Security checks | HTTPS, mixed content | Mixed content, missing headers |
| Post-interaction issues | No (audit ends after load) | Yes (watches all interactions) |
| SEO audit | Yes | No |
| PWA audit | Yes | No |
| CI/CD integration | Yes (CLI, PageSpeed API) | No |
| Cost | Free | Free (2 detectors) / $7/mo (all) |

Verdict
Use Lighthouse when you want a thorough audit of a specific page: performance scores, SEO checks, accessibility compliance. Run it before a launch or as part of your CI pipeline.
Use Hushbug while you develop. It catches the runtime issues Lighthouse misses: errors triggered by user interaction, network failures during form submissions, layout shifts caused by dynamic content. You do not need to remember to run it. It watches in the background and shows you a badge count when something goes wrong.
For most developers, both tools are worth having. Lighthouse for deliberate auditing. Hushbug for passive, continuous monitoring during development.
