Questions
Does UptimeRobot alert on WhatsApp?
Not native (via Zapier or another bridge). In MonitoraWeb it is included in paid plans and goes out from our official WhatsApp Business number, through Meta's API.
What does UptimeRobot do better than MonitoraWeb?
50 free monitors, and its terms allow commercial use. Checks every 15 seconds on its Scale plan. Paid plans can pick a region: North America, Europe, Asia or Australia. SMS and voice call alerts, with credits. A very long list of integrations.
Where does MonitoraWeb check from?
From a single point: our server. That is why each failure is retried after 10 seconds and an outage only counts after three failures in a row. We would rather say so than promise a network of servers we do not have.
