The same checks we run on every monitored site, one at a time. Type a domain and see what your clients' browsers, Google and mail servers see.
Grade from A to F with security, email, domain, SEO and availability in a single shareable report.
See every DNS record of a domain: A, AAAA, CNAME, NS, MX, TXT, SOA and CAA, as our resolver sees them right now.
Registrar, creation and expiry dates, nameservers and transfer lock of any domain. The expiry date is the one that takes sites down without warning.
Is the certificate valid, who issued it, when does it expire and which TLS versions does the server accept.
IP address, country, network and the hosting provider we deduce from it. Also whether the site sits behind a CDN such as Cloudflare.
MX, SPF, DKIM and DMARC. If any of these is missing, anyone can send email in your name, and yours may end up in spam.
HSTS, Content-Security-Policy, X-Frame-Options and the rest: the headers that protect your visitors, with a grade and what is missing.
Where does a URL end up, and through how many hops. Redirect chains slow every visit down and confuse search engines.
Meta robots, X-Robots-Tag header and robots.txt. Launching a site with a "noindex" left over from staging costs weeks of ranking and nobody notices.
We request the site right now from our server and tell you the status code and the response time. No cache, no guessing.
Write a network in CIDR notation and get the mask, the range of usable addresses, the broadcast and how many hosts fit inside.
Build the five fields of a cron line without guessing, read back in plain words what an existing one does, and see when it would run next.
Add your sites and we check them every minute. If something on this page changes, you get a message before your client does.
