How is this not an utterly shameless clone/duplication of https://getcssscan.com/ https://getcssscan.com/? The colour scheme + UI of the tool is almost identical, the first heading "The fastest and easiest way to check, copy and edit CSS" on the homepage is identical, chunks of other text is the same, FAQ questions are identical etc. I can't understand why anyone would put the work into making something like this and not make a minimal effort to at least write their own marketing text and change the colours.
