Show HN: HTML Size Analyzer

Hi HN,

Sometimes when looking into why a website is slow I find that the size of the HTML document is half a megabyte or more.

There's a few reasons for this, often JSON hydration state from a single-page app or inline images that are embedded as data URLs.

Other times there's just lots of duplication, for example a page I saw specified 180 image URLs per visible images (to make it super duper double responsive). Duplicated HTML usually compresses well when sent over the network, but can cause long HTML parse times.

I built this tool to make it easier to identify the cause of bloated HTML code.
