Frequently Asked Questions
Should I Block Trellis-Services?
Only if no one on your team relies on it. Trellis-Services 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 Trellis-Services.
Does Trellis-Services Follow Robots.txt Rules?
No. Trellis-Services 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 Trellis-Services Access Private Content?
Only when configured with access. A team may grant Trellis-Services credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
Why Is Trellis-Services Visiting My Website?
Someone, most likely on your own team, configured Trellis-Services 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 Trellis-Services Is Visiting My Website?
Agent Analytics tracks Trellis-Services 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 "Trellis-Services". Look for repeated checks of the same pages or endpoints at regular intervals. Because Trellis-Services does not publish a verification method, any client can claim its identity and a log match is only a clue.
