Every section has little (i) icons and all of them are useless.<p>For my site it shows under "Site Features" a "root authority". Okay that's new to me, let's see what that means. The full explanation is: "Checks which core features are present on a site." That's like answering "water" when someone asks "what's water?"<p>The use cases section of the info is similarly useless and additionally hyperbolic in most instances, such as: "DNSSEC information provides insight into an organization's level of cybersecurity maturity and potential vulnerabilities". If DNSSEC for one domain can tell me about the overall security maturity of an organisation as well as reveal potential vulnerabilities, please enlighten me because that'd be very useful for redteaming assignments<p>The thing detects January 1st 2008 as the page's content type, which makes no sense (checked with curl, that's indeed incorrect)<p>Server location is undefined at the top of the page (first impression; the section with the map) but later in the server info section it guesses a random city in the right country<p>It reports page energy consumption in KWg. Kelvin×Watt×grams, is this a typo for kWh? One kWh is about as much energy as 50 smartphone batteries can hold, as if a page (as measured by its size in bytes) would ever use that amount of energy. You can download many 4k movies on one smartphone charge (also when considering the power consumption of routers), surely that's not the unit being used to judge html weight?<p>The raw json results, where I was hoping fields might have clearer (technical) labels than the page, remains blank when trying to open it<p>Overall, I'm not sure what the intended use of this site is. It presents random pieces of information with misleading contextualisation and no technical explanation, some of which show incorrect values and many of which don't work (failing to load or showing error values like undefined). Maybe tackle it in sections, rethinking what the actual goal is here and, once you've identified one, writing that goal into the "use cases" section and implementing it, finally writing in the "what is this" section what it is the site is checking for, then repeat for the next useful piece of information you can come up with, etc.
