UptimeGlass vs HetrixTools
HetrixTools monitors uptime every minute from up to 12 locations, also on its free plan, and adds server and blacklist monitoring.
Where HetrixTools is stronger
- 1-minute checks on the free plan (15 monitors).

Where UptimeGlass is stronger
- Reads WordPress errors behind "200 OK": database connection errors, critical errors and PHP fatal errors.
- The plugin reports database health, WP-Cron and the last fatal error with the plugin it came from.
- WordPress maintenance is shown as maintenance, not downtime; a stuck update gets one alert.
- Update Guard names the update that broke a site.
- Connects a site in one click from the WordPress admin.
