Lighthouse Monitoring

Lighthouse monitoring runs Google's Lighthouse audit against your page on a schedule and tracks the scores over time. It's how you catch a front-end regression — a heavy new hero image, a render-blocking script, a broken meta tag — before it quietly erodes your Core Web Vitals and your search ranking.

How it works

On each run UptimeStatus loads your page in a headless browser and runs a full Lighthouse audit, capturing the four category scores (0–100):

• Performance — including Core Web Vitals: LCP, CLS, TBT.
• Accessibility
• Best Practices
• SEO

Scores and the underlying metrics are stored so you can chart trends and compare a run against the previous baseline. Because a full audit is heavier than a simple fetch, Lighthouse runs on a longer cadence (typically daily, configurable).

What triggers an alert

• Any category score drops below a minimum threshold you set (e.g. Performance < 80).
• A regression versus the last run / baseline larger than your tolerance (e.g. Performance fell 15+ points).
• A specific Core Web Vital crosses its threshold (e.g. LCP > 2.5s).

Each alert links to the full report so you can see exactly which audits regressed.

Setting it up

1. Add monitor and choose Lighthouse.
2. Enter the page URL to audit.
3. Choose the device profile (config device: mobile or desktop, default mobile) and cadence. Desktop uses Lighthouse's desktop preset (form factor, screen emulation, and throttling together).
4. Set minimum scores and regression tolerances per category.
5. Attach notifications.
