Run your speed test
Enter a URL and we'll load the page, measure every request, and grade its performance.
A Pingdom-style speed test — performance grade, load time, page weight, HTTP requests, and a full content breakdown by type and domain.

The four numbers that explain how a page performs.
Everything you need to know about this speed test.
Each insight (requests, page weight, images, minification, render-blocking, CDN use, redirects, compression and TTFB) earns points toward a 0–100 score. The grade is A (90+), B (80+), C (70+), D (60+) or F (below 60).
The test runs entirely in your browser through public CORS proxies, so results reflect the proxy route and your own connection. Raw timing numbers are a relative guide — focus on the grade and the breakdown, which are consistent.
To keep the test fast, resource downloads are capped and run in parallel with a per-request timeout. Slow, blocked, or third-party resources past the cap are listed but marked as not measured.
No. The proxy can only reach publicly accessible pages. Logged-in or paywalled content will fail to load.
