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.
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. For context, 7% of the top websites we track currently have robots.txt rules for Checkly.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Checkly?
Checkly's traffic often follows fixed intervals like a cron job. Activity may consist of short recurring checks or occasional intensive bursts, but it usually remains limited to a specific set of pages or endpoints.
Does Checkly Follow Robots.txt Rules?
No. Checkly 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.
Is Checkly Used for AI Model Training?
Not ordinarily. Checkly is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Checkly Affect AI Search or Citations?
Not directly. Checkly's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
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.
How Can I Verify a Request From Checkly?
Agent Analytics tracks Checkly visits in real time. 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.
How Is Checkly Different From Other Checkly Agents?
Checkly operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
