Expected Behavior

Chirp's traffic is as regular as a cron job, because it usually is one. Uptime monitors hit the same endpoint every few minutes, while performance and audit tools run deeper scans on demand. Expect narrow, repetitive access to specific pages rather than crawling.

Frequently Asked Questions

Should I Block Chirp?

Only if nobody you work with uses it. Chirp is the kind of tool a team points at its own site for uptime checks, performance tests, and audits. If someone on your team relies on it, blocking it silently breaks their monitoring. Almost none of the top websites we track have robots.txt rules for Chirp right now.


Does Chirp Follow Robots.txt Rules?

No. Chirp is not expected to follow robots.txt rules, so a disallow rule only states your preference. Enforce the block with firewall or server rules, then confirm in Agent Analytics that its requests actually stop.


Does Chirp Access Private Content?

Only if its owner sets that up. Monitoring tools check whatever they are configured to check, which can include staging sites and private health endpoints when a team grants access. Uninvited, Chirp sees only public pages.


Why Is Chirp Visiting My Website?

Someone pointed Chirp at your site, most likely your own team. Uptime monitors, performance testers, and audit tools only visit the sites they are configured to watch.


How Can I Tell if Chirp Is Visiting My Website?

Agent Analytics tracks Chirp 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 "Chirp". Look for regular checks of the same pages or endpoints, often minutes apart. Keep in mind that Chirp doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
