LiveFind the scripts, styles and images weighing down a page.

Requirements
- • A ToolCargo account with Site Audit activated (free).
- • A public HTML page whose robots policy permits access.
Limitations
- • HEAD checks only six same-origin assets; external assets are counted but not requested.
- • Content-Length may be absent or differ from actual browser transfer. No JavaScript execution or load timing.
- • One 500 KB HTML page plus at most six HEAD requests, each at most four seconds; redirects and unknown robots policy are refused.
