About LabPuff
LabPuff — an independent project.
LabPuff is a collection of free tools for understanding website responses, DNS, email policies and crawl settings. Reports describe what our server observed and explain the limits of each check.
Our diagnostic user agent
Requests identify themselves as LabPuff/1.0 and link to this page. A visitor initiates each check. The service requests the submitted public URL and, for a full check, /robots.txt and /sitemap.xml. It follows up to five public redirects; it does not crawl every page or run scripts.

Please include the affected domain, time of the request and a description when reporting unwanted diagnostic traffic or incorrect findings. Avoid sending credentials or private URLs.
