Should I Block Sentry?
Probably not. Developer helpers are normally used to optimize or find problems with your website.
How Do I Block Sentry?
⚠️ 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.
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.
