UptimeGlass vs OnlineOrNot
OnlineOrNot checks websites, APIs and cron jobs and can run browser checks. The free Hobby plan has 3 monitors.
Where OnlineOrNot 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.
