Free website performance test
A no-sign-up check for any public URL—quality scores, speed metrics, and fix ideas to ship faster pages. Use it to bring teams in; when you need 24/7 monitoring and alerts, UptimeMatrix picks up where one-off tests end.
No sign-up—enter a public URL for an instant performance report: category scores, speed and stability metrics, and prioritized improvements. Pair one-off checks with UptimeMatrix for always-on monitoring and alerts.
What this is (and is not)
This report combines a simulated lab run with real-user field data when samples exist for the URL or your site. Use it for before/after deploy checks and budgets. It is not a replacement for high-concurrency load testing—pair it with UptimeMatrix for production signals.
