What is Nutch?

About

Nutch is a scraper. If you think this is incorrect or can provide additional detail about its purpose, please contact us. You can see how often Nutch visits your website by setting up Dark Visitors agent analytics.

Expected Behavior

Due to the wide variety of use cases, there's no way to accurately predict visitation behavior. Scrapers are notorious for ignoring robots.txt rules and accessing disallowed content. This is especially true if they're dispatched to achieve a specific goal rather than for some general purpose.

Should I Block Nutch?

Probably. Scrapers usually download publicly available internet content, which is freely accessible by default. However, you might want to block them if you don't want your content to be used for unauthorized purposes.

How Do I Block Nutch?

⚠️ Manual Robots.txt Edits Are Not Scalable
New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.
Set Up Automatic Robots.txt

You can block Nutch or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
