Free tools to check any website
Is it up? Is the SSL certificate about to expire? Will your email land in spam? Find out in a few seconds, in plain English. No sign-up.
Full check
Free website check: see if a site is up, whether its SSL certificate and domain are about to expire, and if its DNS, SPF and DMARC are set up right. No sign-up.
SSL checker
Check a website's SSL certificate: when it expires, who issued it, whether it covers the domain and whether browsers trust its chain. Free, no sign-up.
DNS lookup
Look up every DNS record for a domain (A, AAAA, CNAME, MX, NS, TXT, CAA and SOA), with a plain-English note on what each one does and common problems.
DMARC & SPF
Check a domain's SPF, DKIM and DMARC records, get a plain-English grade and the exact DNS record to add so your email stays out of spam and can't be spoofed.
Is it down?
Is a website down for everyone or just you? Pingerer checks it right now from our servers and tells you what it answered, in plain English.
Domain expiry
Look up when a domain expires, who it's registered with and whether its transfer lock is on, straight from the registry over RDAP. Free, no sign-up.
Why these checks matter
Most website problems aren't the server crashing. They're a certificate nobody renewed, a domain whose card expired, a DNS change that broke email, or a missing DMARC record that quietly sends your invoices to spam. Each of these tools checks one of those things right now, from our servers, and tells you what to do about it.
The tools don't save anything about the sites you check, and they don't set tracking cookies. Results are kept for a few minutes so a shared link opens instantly.
Checking the same things every week?
That's what Pingerer is for: it runs these checks for you around the clock and tells you by email, Slack or text the moment something changes. Start free with one domain and every check, then pay per domain when you need more.
