How this service works
Page weight and resource inventory from the HTML: document bytes, script/stylesheet/image/iframe/font counts, inline script bytes, external hosts contacted, and a simple heaviness verdict. A quick performance smell test without a browser. $0.01 per page.
Output
Returns document byte size, counts of scripts, stylesheets, images, iframes, and fonts loaded by the page, the volume of inline script bytes, a list of external hosts contacted, and a simple 'heaviness' verdict indicating whether the page is considered too heavy for good performance.
Example use cases
Pre-launch performance smell test
“Before we go live, can you check the page weight and resource counts on https://myapp.com/landing — I want to know if it's too heavy, how many external hosts it's hitting, and roughly how big the document is?”
Competitor page bloat audit
“Can you analyze https://competitor.com for page weight? I want to see how many scripts, stylesheets, images, and fonts they're loading, and whether they'd get a heavy verdict.”
Monitoring a CMS page for resource creep
“Check https://myblog.com/home and tell me the full resource inventory — script count, image count, external hosts contacted, and inline script bytes — so I can see if it's gotten bloated since last month.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/site/weightWhen to prefer
Use this endpoint when you need a fast, lightweight check on a page's resource footprint without spinning up a headless browser. It's ideal for quick performance audits, detecting resource bloat, or inventorying external host dependencies from raw HTML. Prefer this over full browser-based tools when speed and cost matter and dynamic JS rendering is not required.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty resource counts
- Page requires JavaScript rendering to load resources — static HTML fetch will miss dynamically injected assets
- Page blocks non-browser user agents — request may be rejected or return minimal HTML
- Redirect chains may not be fully followed — final destination resource inventory may differ from expected
- Very large HTML documents may result in incomplete parsing or timeouts
