WakeMetric monitors three things on the free Community Plan: website uptime (whether your site returns a successful HTTP response), SSL certificate expiry (how many days remain before your certificate expires), and domain expiry (how many days remain before your domain registration renewal date).
WakeMetric's external cloud infrastructure checks your site's HTTP response every 15 minutes from monitoring nodes in multiple global regions. If your site returns an error code or becomes unreachable, you receive an email alert. A follow-up email confirms when your site is back online.
Self-hosted monitoring plugins run on your WordPress hosting server. If your server crashes, runs out of memory, or encounters a fatal PHP error, the plugin cannot run and cannot send a downtime alert. WakeMetric checks your site from outside your server, so you are alerted even if your server is completely offline.
WakeMetric reads your SSL/TLS certificate's expiry timestamp by connecting to your site from our cloud servers, the same way a visitor's browser would. You receive advance email alerts at 30 days, 14 days, and 7 days before expiry, giving you time to renew before visitors see browser security warnings.
WakeMetric queries authoritative WHOIS and RDAP registries to identify your domain's renewal date. You receive advance email alerts before your domain expires, enters a redemption period, or risks being released for re-registration.
Yes. The Community Plan includes 15-minute uptime checks, SSL certificate expiry alerts, domain expiry monitoring, and email alerts at no cost, with no trial period, no expiry date, and no credit card required.
No separate account registration is needed. You connect the plugin by entering your alert email address and clicking Connect. WakeMetric creates a monitoring account automatically using your site URL and email.
The plugin sends your site URL, site name, alert email address, WordPress version, plugin version, PHP version, and server locale. This information is used only to set up and operate your monitor and send alert emails. WakeMetric does not collect, store, or transmit passwords, database credentials, post content, customer data, or personal information about your visitors.
No. All uptime checks, SSL inspections, and domain lookups are performed externally by WakeMetric's cloud infrastructure. The plugin makes lightweight API requests to fetch your current monitoring status when you view the dashboard, using a local cache to minimise API calls.
Click Disconnect Site on the WakeMetric settings page to stop monitoring at any time. When you delete or uninstall the plugin from WordPress, all locally stored data — API keys, options, transients, and scheduled tasks — is permanently removed from your database.
WakeMetric currently supports single-site installations. Network-wide multisite activation is planned for a future release.
WakeMetric requires WordPress 6.4 or higher and PHP 7.4 or higher. It has been tested up to PHP 8.4 and WordPress 7.1.
