WebReveal
Tells you what a site is built with, free backlink

Biggest thing: I have no idea why I'd pay for this when Wappalyzer and BuiltWith exist and are free. Your page lists six feature categories but never tells me what's different. You claim 97% accuracy and 620+ technologies — cool, but compared to what? Without that, the 'Get more scans' upsell is a tough ask. The scan input right on the page is smart — low friction to try. But 'join hundreds of developers' is underselling or revealing low traction. Consider adding a comparison table against competitors and showing a sample scan result on the landing page so people see value before they type a URL.
ok so the big thing here is -- why would i use this over BuiltWith or Wappalyzer... the page looks clean, really clean actually, nice design work but it never answers that question and thats kind of the whole ballgame right? you say "97% accuracy" but compared to what -- that claim floats there with no backing. the hero works fine mechanically, scan box right there, instant value prop... but "Reveal the Tech Stack Behind Any Website" is exactly what 4 other tools already say. "join hundreds of developers" -- id maybe not advertise hundreds when your competitors have millions, it makes you sound small. source code analysis keyword search is actually interesting and i almost missed it buried as the 6th card -- that might be your differentiator, consider leading with it. also no pricing anywhere so i dont know if this is free or paid
