Free Website & DNS Checker

Is a website down? Is its SSL certificate about to expire? Are the DNS records right? Check up to 20 sites at once.

Quick human check, then the tool unlocks:

Domains or URLs (one per line)

Website check (status, speed, SSL, redirects) DNS records

What this checker shows

Up or down: the HTTP status code and how fast the site responds from our server.
Redirects: every step from the address you typed to the final page.
SSL certificate: who issued it, when it expires, and whether browsers trust it.
DNS: A, AAAA, CNAME, MX, NS, TXT (including SPF), SOA, CAA and DMARC records.

🔒 The domains you check are not saved or logged by this tool.
