The $9 uptime monitor
that does 16 more things.
Minute-interval uptime checks, keyword/health/status monitoring, and public status pages — bundled with SSL, headers, DNS, leak detection, and every scan you need. Free forever tier, no credit card.
Uptime alone isn't enough.
A site that's up but leaking credentials, serving vulnerable scripts, or running expired SSL is still broken. One tool should catch all of it.
60-second uptime checks
Health, keyword, and status-code monitoring from multiple regions. False-positive guard with multi-location verification.
16 security scans bundled
SSL expiry, DNS, headers, vulnerabilities, leaked credentials, third-party scripts. Every scan, same dashboard, one bill.
Public status pages
Branded, white-label status pages on your own subdomain. Keep customers informed without PagerDuty or Statuspage.io.
Paying for uptime-only? Here's the gap.
Most dedicated uptime tools stop at "is it up?" You get pinged when the site's down. That's it. No vulnerability scan, no SSL expiry warning, no leaked-credential check.
