HTTP Requests Checker
Every file a page references is another request for the browser. The tool reads the HTML and counts the resources it loads, grouped by type.
Checked by our server, free and without an account

What the tool looks at
- Number of scripts, stylesheets, images and other resources.
- The total number of requests referenced in the HTML.
How it works
- Enter the address. Only public web addresses on the standard ports are accepted.
- Our server fetches what the check needs once, with its own honest bot name, and evaluates it.
- You get the evaluated values with a short explanation. Nothing from the page is stored.
More Performance tools
All tools- TTFB CheckerMeasure the time to first byte of a page – how quickly the server starts to answer.
- Page Size CheckerCheck how large the HTML of a page is – transfer size and uncompressed size, with a rating.
- DOM Size CheckerCount the HTML elements of a page – a large DOM makes rendering and interaction slower.
- HTTP/2 CheckerCheck whether a website is served over HTTP/2 – faster loading of many files over one connection.
- Compression CheckerCheck whether a server compresses its pages – Gzip, Brotli or Zstandard, or none at all.
- Brotli CheckerCheck whether a server supports Brotli compression – usually smaller than Gzip for text files.
- JavaScript Defer CheckerFind scripts that block rendering – external scripts without defer or async in the HTML of a page.
- Image Format CheckerCheck whether the images of a page use modern formats such as WebP or AVIF instead of large JPEG and PNG files.
- Lazy Loading CheckerCheck whether the images of a page are lazy loaded – images further down only load when they are needed.
The whole page in one audit
One audit runs more than 50 tests, rates them by severity and turns them into a score. Websites are re-checked on a schedule.
