# Guardr

> Website health monitoring for the sites you manage. Guardr checks uptime every minute from three global regions, tracks certificate expiry, reads response headers and DNS records, then reports a health grade with a fix for every finding. Checks run from outside the site. Nothing is installed on a server.

Guardr watches a site continuously rather than auditing it once. The free plan is the whole product on one site. Further sites are $3.00 each per month.

- check_site: a fresh check of one domain, with the grade and the findings.
- list_sites: the sites your account watches.
- get_site: one watched site in detail.
