Crawler

HowItsBuiltBot

HowItsBuiltBot fetches a website's homepage when someone looks it up on howitsbuilt.fyi, to detect which technologies it uses.

How it behaves

  • User agent: Mozilla/5.0 (compatible; HowItsBuiltBot/1.0; +https://howitsbuilt.fyi/bot)
  • One request for the homepage per lookup, following at most 3 redirects. No crawling of other pages.
  • Results are cached for 24 hours, so a site is fetched at most about once a day per lookup.
  • It only runs on user request; it does not crawl the web on its own.

Opting out

If you would rather not be looked up, e-mail lucas@lkmedia.net with your domain and we will exclude it.
