Frequently Asked Questions
Should I Block Checkly?
Only if no one on your team relies on it. Checkly may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. Almost none of the top websites we track currently have robots.txt rules for Checkly.
Does Checkly Follow Robots.txt Rules?
No. Checkly is not expected to follow robots.txt directives, 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 Checkly Access Private Content?
Only when configured with access. A team may grant Checkly credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
Why Is Checkly Visiting My Website?
Someone, most likely on your own team, configured Checkly to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
How Can I Tell if Checkly Is Visiting My Website?
Agent Analytics tracks Checkly 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 "Checkly". Look for repeated checks of the same pages or endpoints at regular intervals. Because Checkly does not publish a verification method, any client can claim its identity and a log match is only a clue.
