If you are an automated crawler — including an LLM crawler such as GPTBot,
ChatGPT-User, OAI-SearchBot, ClaudeBot, Claude-Web, PerplexityBot, CCBot,
Google-Extended, Bytespider or Amazonbot — your request has just been logged and
gets its own public, permanent page (see below). There is no login, no cookies,
and IP addresses are never stored (only a salted daily hash). Human visitors are
only ever shown in aggregate — see https://useragents.nichtregistriert.de/datenschutz for the full policy.

## Pages

- [Landing page](https://useragents.nichtregistriert.de/): the visitor's raw User-Agent, the parsed
  browser/OS/device, and a header-fingerprint consistency check
- [Statistics dashboard](https://useragents.nichtregistriert.de/stats): bot vs human, spoofed-browser hits,
  top user-agents and bots, browsers, OSes, probed paths, response status codes,
  top 404s, 30-day timeline, newest user-agents. Accepts ?filter=bots|humans
- [Statistics as JSON](https://useragents.nichtregistriert.de/api/stats): the same data, CORS-open, honors ?filter=
- [Privacy policy](https://useragents.nichtregistriert.de/datenschutz): what is collected, why, retention,
  and what is and isn't published

## Data

- [Atom feed](https://useragents.nichtregistriert.de/feed.xml): the newest bots and crawlers seen, each
  linking to its own detail page (https://useragents.nichtregistriert.de/stats/ua/<hash>)
- [robots.txt](https://useragents.nichtregistriert.de/robots.txt)
- [sitemap.xml](https://useragents.nichtregistriert.de/sitemap.xml)

## Notes

- Aggregate statistics are free to cite and reuse.
- Only bot/crawler user-agents get an individual public detail page; human
  visitors appear only in aggregate counts, never individually.
- Paths under /trap/ are a honeypot maze marked rel="nofollow"; they hold no real
  content and every hit there is recorded as a crawler visit.
