Paste HTML, list every script and stylesheet blocking first paint. Everything runs locally in your browser, nothing is uploaded.
About this tool
Blocking scripts and CSS delay first paint. See exactly what is blocking and in what order.
Why free, and what happens next
Tools like this one are how this desk stays findable: useful first, commercial when you are ready. When a tool surfaces a problem you would rather have fixed than diagnosed, start a project or run the cost calculator first. Everything runs client-side: your data never leaves this page.
