As mentioned in my previous comments, here's why we think we have something different (and maybe better) than our counterparts like Wappalyzer:
1. WhatRuns detects fonts, Wordpress plugins and themes (tens of thousands of them).
2. Ability to follow sites (and know what techs websites started using/ditched).
3. Very lightweight compared to our counterparts, and arguably better UI ;)
4. More accurate data. BuiltWith can be very inaccurate as you might've already noticed. Wappalyzer is fairly accurate, but limited in technologies. WhatRuns is trying to be the best of both worlds.
