What is Chirp?
Chirp is a monitoring bot operated by Binary Canary, a website and server uptime monitoring service that has been operating since 2010. The bot checks websites to detect downtime and ensure they remain accessible from multiple monitoring locations. You can set up Agent Analytics to see when Chirp visits your website.

Why Is Chirp Visiting My Website?
Someone, most likely on your own team, configured Chirp 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 Chirp?
Only if no one on your team relies on it. Chirp 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 Chirp.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Chirp?
Chirp'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 Chirp Follow Robots.txt Rules?
No. Chirp 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 Chirp Used for AI Model Training?
Not ordinarily. Chirp is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Chirp Affect AI Search or Citations?
Not directly. Chirp's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Chirp Access Private Content?
Only when configured with access. A team may grant Chirp credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
How Can I Verify a Request From Chirp?
Agent Analytics tracks Chirp visits in real time. You can also check your server logs for requests whose user-agent string contains "Chirp". Look for repeated checks of the same pages or endpoints at regular intervals. Because Chirp does not publish a verification method, any client can claim its identity and a log match is only a clue.
How Is Chirp Different From Other Binary Canary Agents?
Binary Canary operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
