SSL certificate checker
Check a site's SSL certificate: who issued it, which names it covers, whether browsers trust it, and how many days are left before it expires. Free, no sign-up.
Know 30 days before the certificate does.
Barkme re-checks every certificate on your verified domains daily and warns you 30, 14, 7 and 1 day before it expires, by email, Slack or Telegram. Free plan included.
What we check
Every check, and why it matters.
Website over HTTPS
We make one HTTPS request to your homepage and record the status code and how long the server took to answer.
Why it matters. If the homepage errors or times out, every visitor and every search crawler sees the same thing. It is the first thing to check when someone says your site is down.
SSL certificate
The certificate your server presents: who issued it, which names it covers, whether browsers trust it, and when it expires.
Why it matters. An expired or mismatched certificate puts a full-page security warning in front of your site, and most visitors will not click past it. Automatic renewal fails more often than people expect.
Reading the results
Five verdicts.
- Pass
- Healthy. Nothing to do.
- Warning
- Works today, but worth fixing before it causes trouble.

- Broken, or about to break. Fix these first.
- Info
- Optional or informational. Not a problem.
- Not checked
- We did not get a clear answer. It says nothing bad about your domain - try again later.
What we do - and don't
A light touch.
- One HTTPS request to the homepage. No crawling, no port scanning, no load testing.
- Private and internal network addresses are never contacted.
- Results are kept for 24 hours so you can share the link. We do not record who ran the check.
