Uptime Monitoring for WordPress Sites
Monitor your WordPress site from outside your server. No plugins to slow down your site. Detect downtime, SSL issues, and performance problems before visitors notice.
WordPress Sites Have Unique Challenges
Plugins, themes, updates, and shared hosting create reliability issues that basic server monitoring misses.
Plugin Conflicts
A plugin update can break your entire site. External monitoring detects these issues immediately, while internal solutions may fail silently along with WordPress.
White Screen of Death
PHP errors and memory limits cause blank pages. Your server reports "200 OK" but visitors see nothing. Content validation catches what HTTP status codes miss.
Shared Hosting Limits
Cheap hosting suspends accounts without notice when you exceed resources. External monitoring alerts you before your host sends an explanation email.
Auto-Update Failures
WordPress core, plugins, and themes auto-update in the background. Sometimes they break things. Monitoring ensures you know within minutes, not hours.
Why External Monitoring Beats Plugins
WordPress monitoring plugins run inside WordPress. When WordPress crashes, the plugin crashes too. External monitoring works independently of your site.
Zero Server Load
No database queries. No PHP execution. No impact on your site's performance or hosting resources.
Works When WordPress Fails
Database connection errors, PHP crashes, and fatal exceptions are detected because we check from outside.
Real User Perspective
We load your site like a real visitor from multiple global locations. If we can't reach it, neither can your users.
No Security Risks
No plugin code in your WordPress installation. Nothing that can be exploited if a vulnerability is discovered.

Frequently Asked Questions
What is WordPress uptime monitoring?
WordPress uptime monitoring is an external service that periodically checks your WordPress site from outside your server to verify it is accessible to visitors. Unlike WordPress plugins, external monitoring continues to work even when WordPress itself crashes, making it the most reliable way to detect downtime.
Do I need to install a WordPress plugin to use AlertSleep?
No. AlertSleep requires no WordPress plugin installation. You simply enter your site URL in the dashboard and monitoring begins immediately. This means zero impact on your site performance and no additional attack surface from plugin code.
How often does AlertSleep check my WordPress site?
AlertSleep checks your WordPress site as frequently as every 1 minute on paid plans, and every 5 minutes on the free plan. Checks are performed from multiple global locations to confirm real downtime before sending alerts.
What alerts will I receive when my WordPress site goes down?
You can receive alerts via email, SMS, and phone calls. Phone call alerts are especially useful for critical WordPress sites — they wake you up in the middle of the night if your site goes down. You can also configure Slack and webhook integrations.
Can AlertSleep detect the WordPress "White Screen of Death"?
Yes. The White Screen of Death returns HTTP 200 (OK) but shows a blank page — which basic ping monitoring misses. AlertSleep can check for specific content on your page, so if a PHP error causes a white screen, you will be alerted even though the server technically responds.
How is AlertSleep different from WordPress monitoring plugins like Jetpack?
WordPress monitoring plugins run inside WordPress. When WordPress crashes — due to a database failure, PHP error, or plugin conflict — the monitoring plugin crashes too. AlertSleep runs externally and is completely independent from your WordPress installation, so it always detects failures regardless of what caused them.
Will monitoring slow down my WordPress site?
No. AlertSleep makes a lightweight HTTP request to your site URL at the specified interval — exactly like a single visitor loading your page. There are no database queries, no PHP code running on your server, and no persistent connections. The impact is negligible.
Is there a free WordPress uptime monitoring plan?
Yes. AlertSleep's free plan includes 5 monitors with 5-minute check intervals and email alerts. This covers most small WordPress sites. Paid plans add 1-minute checks, SMS/phone alerts, and SSL certificate monitoring starting at a low monthly cost.
