Should I Block Sentry?

Probably not. Developer helpers are normally used to optimize or find problems with your website.

How Do I Block Sentry?

You can block Sentry 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.

How Do I Block All Developer Helpers?

Serve a continuously updating robots.txt that blocks new developer helpers automatically.

Set Up Automatic Robots.txt

# In your robots.txt ...

User-agent: Sentry # https://darkvisitors.com/agents/sentry
Disallow: /

⚠️ Manual Robots.txt Editing Is Not Scalable

New agents are created every day. We recommend setting up Dark Visitors Automatic Robots.txt if you want to block all agents of this type.
