WEBSITE MONITORING AND TESTING · QUEBEC
TestRaptor captures, compares and keeps every state of your site. Checks aren't metered and history never expires.

A certificate check costs a handful of kilobytes: one TLS handshake, six DNS queries, one RDAP query. Our competitors sell it by the monitor because it lives on a monitoring platform rented by the monitor. Ours runs on a machine already paid for, in Quebec. That's why we count your domains and not your checks, and why we keep history instead of cutting it off at three months.
UptimeRobot warns you 30, 14 and 7 days before expiration. We warn at 60, 30, 14, 7, 3 and 1 day, and immediately if your NS or MX records change, because an NS change you didn't ask for is a domain hijacking in progress.

The “not published” columns mean the service doesn't state a retention period on its pricing page, not that it has none. Found an error? Write to us, we'll fix it and re-date it.
Beyond the ping
An uptime monitor only checks that an endpoint responds. We monitor the TLS certificate, the DNS records and the domain's expiry date — and tell you what to do before it breaks.
