Website Speed Checker
We download your page and every file it references from our own servers, so the weights and timings are real measurements rather than an estimate.
Every check this tool runs.
Nothing here is a black box. Each row is a real measurement, and the report tells you how each one was worked out.
Page weight
Total transferred bytes, split into HTML, CSS, JavaScript, images and fonts.
Response time
Time to first byte, plus how long the HTML took to download.
Redirects
Every hop, because each one costs a visitor a round trip.
Compression
Whether the HTML arrived gzipped or brotli compressed.
Requests
How many files the page needs, and which block rendering.
Third parties
How many external domains the page depends on.
Core Web Vitals
From Google when available, clearly marked as not measured when not.
Want it fixed rather than just measured?
Send us the report. We will work through it in priority order and tell you which changes are worth making and which are not.
