How works
- 1
Enter any public URL
Paste a full URL including path — e.g. https://example.com/blog/post. The tool tests that exact page.
- 2
Pass a quick security check
Cloudflare Turnstile verifies you are human before the test runs. This is usually invisible and takes less than a second.
- 3
Analysis runs in parallel
We fire three requests simultaneously: Google PageSpeed Insights for desktop, Google PageSpeed Insights for mobile, and a direct server fetch for TTFB and headers.
- 4
Review results and insights
Scores, Core Web Vitals, server details, and prioritised fixes appear together. High-impact issues are listed first.
URLs are sent to Google PageSpeed Insights API for analysis. No results are stored. Rate limits (5 tests/hour per user, 3 tests/day per domain) are enforced server-side.
