Audit de performance

Quick load-time and weight check for any public URL.

Runs in your browser

A focused subset of what Lighthouse measures — TTFB, total time, weight, compression and two security headers. The full Lighthouse needs a headless browser; we ship the part you can do from the page.

Run an audit to see the headline grade and per-metric breakdown.

Questions fréquentes

Quick answers.

›How does this differ from the official Lighthouse tool?

This provides a lightweight simulation of the core performance metrics without the deeper accessibility or SEO auditing. It is designed for quick checks of page weight and load speed rather than full development reports.

›Can I audit local or private URLs?

No. Because our server must fetch and render the page to calculate performance, the URL must be publicly accessible on the internet.

›Is the audit data stored or tracked?

We do not store the results of your audit or the URLs you test. The data is processed in real-time and exists only in your current browser session.

›Why do mobile and desktop scores differ?

Mobile audits use a throttled network connection and slower CPU simulation to reflect real-world handset performance. Desktop audits assume a faster connection and more efficient hardware.
