UptimeGlass vs UptimeRobot
UptimeRobot is a general uptime monitor with a generous free plan: 50 monitors checked every 5 minutes, also for commercial use. It checks any URL the same way and does not look inside WordPress.
Where UptimeRobot is stronger
- More monitors on the free plan (50) than our Free plan.
- Monitors any URL, port or keyword, not only WordPress sites.
- Faster checks on its larger plans (down to 15 seconds on Scale).
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.
