Check your website
before your customer does
Five checks that answer the most common questions about a website: is it up, is the certificate still valid, when does the domain expire, is your email protected and does the server send security headers. No account, no email address.
We check from the outside, exactly like an ordinary visitor. We need no access to your site.
Is my website down
Check from the outside whether the site responds, and whether the problem is on your end.

SSL certificate
Expiry date, issuer, name coverage and everything else that makes the padlock disappear.
Open the tool ›
Domain expiry
When the domain expires, who the registrar is and whether anyone can move it without your knowledge.
Open the tool ›
SPF, DKIM and DMARC
Why your email lands in spam, and whether someone can send invoices from your address.

Security headers
Eight items you set on the server in a quarter of an hour, and every audit asks about them.

Why this matters
All of these fail quietly. A certificate expires overnight, a domain expires because the invoice went to a mailbox nobody reads, and nobody looks at security headers until a client sends an auditor. A tool tells you how things are today. Monitoring tells you the moment they change.
You checked once. We check every five minutes.
The free plan watches your home page, the SSL certificate and the domain expiry date. No card, no expiry date on the plan itself.
- A pulse check every 5 minutes, with a second check confirming an outage
- A warning before the certificate and the domain expire
- Email notifications with no limit
- Seven days of statistics, one account
