Uptime · SSL · Domains
Know when your website is down, and when its certificate or domain is about to expire.
Certwatch checks your websites every 10 seconds, inspects SSL certificates every hour, and refreshes domain registration and DNS details daily. Monitoring keeps running while you are signed out.
Every new subscription is reviewed and approved by a super admin before payment. You are never charged for a request that is not approved.
What you get

HTTP status and response time every 10 seconds, with confirmed incidents and recovery alerts.
SSL expiry monitoring
Hourly certificate checks and alerts at thresholds you choose, such as 30, 14, 7 and 1 days.

Honest status, not guesses
A website with an expired or untrusted certificate that still answers HTTP requests is reported as Up, and the certificate problem is shown separately under SSL status. A login-protected page that answers 401 or 403 is shown as Access restricted, not Down.
If checks stop running, results are marked Stale. Missing measurements are never treated as downtime.
Security built in
- Two-factor authentication required for every account
- Each customer sees only their own data
- Card details are handled by the payment provider and never stored here
- Domain ownership verification before sustained monitoring
- Monitoring never probes private or internal networks
