nextdoor.com looks like a forum or community, is ranked in the top 10,000 sites and was registered in 2004. We couldn’t read its page: its robots.txt asks bots like ours to stay away.

This site asks bots like ours not to read its pages, so we didn’t. What public records say is below; the score needs the page.

Built with AI?

AI Website Detector

We couldn’t read the page, so we couldn’t look for traces.

AI traces: Couldn’t check

How we know

AI site builders leave traces in the sites they make. We look for the traces of 53 of them and show every match with the line it came from, so you can check it yourself.

We test this on 2,312 sites whose makers we know, and publish what we get wrong.

  • With sources. Every fact above says where it came from and when.
  • Without guessing. When we couldn’t check something, we say so.

Automated findings from the site’s public home page and public records, as of 13 Oct 2026. They describe what we found, not the people or business behind the site, and they may be incomplete or out of date. This is information, not advice. Terms · Report an error

What this scan can’t tell you
  • Whether the business is real, honest or delivers what it sells.
  • Whether a site was made with AI when no traces were left: coding assistants and hand edits leave none.
  • How many people visit: we show popularity bands from public lists, not visits.
  • Anything beyond the home page as it was at the time of the scan.
