Frequently Asked Questions
Should I Block Rigor?
Only if no one on your team relies on it. Rigor may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. For context, 6% of the top websites we track currently have robots.txt rules for Rigor.
Does Rigor Follow Robots.txt Rules?
No. Rigor is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Does Rigor Access Private Content?
Only when configured with access. A team may grant Rigor credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
How Can I Tell if Rigor Is Visiting My Website?
Agent Analytics tracks Rigor visits in real time. You can also check your server logs for requests whose user-agent string contains "Rigor". Look for repeated checks of the same pages or endpoints at regular intervals. Because Rigor does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is Rigor Visiting My Website?
Someone, most likely on your own team, configured Rigor to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
