What is KunatoCrawler?

Be skeptical. Zzazz has not documented what KunatoCrawler collects or why, so you cannot weigh any benefit against the cost. Assume collected content can end up in AI training data, and block it if its traffic gets heavy. Blocking it will not change your search rankings. For comparison, 2% of the top websites we track already have robots.txt rules for KunatoCrawler.

Yes. KunatoCrawler is expected to follow robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms KunatoCrawler actually follows it.

Unknown. Without documentation there is no stated boundary and no way to hold the operator to one. Assume KunatoCrawler reads anything publicly reachable, and verify that your sensitive areas actually require authentication.

There is no documented answer. The realistic possibilities are training data collection, index building, or an experiment Zzazz has not announced. KunatoCrawler's request pattern on your site is the best clue you will get.

Agent Analytics tracks KunatoCrawler visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "KunatoCrawler". Watch both its volume and its targets, since neither is documented. Keep in mind that KunatoCrawler doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
