Site Monitor, UptimeRobot or Better Stack?
For: Watching one business website for outages and SSL expiry, with email alerts and checks at least every five minutes.
The short answer
- Subscription difference
- Not comparedSubscription only, at the dated prices below
- Main advantage
- Site Monitor’s value is fit, not price: monitoring on the same account and invoice as your other Adiuvo tools, with incident history and maintenance windows.
- Main trade-off
- At the dated prices below, Site Monitor costs more than both free plans, which also include more monitors.
For uptime checks on their own, UptimeRobot’s and Better Stack’s free plans cover more sites and check more often than Site Monitor, at no subscription cost. Site Monitor fits when you want monitoring on the same account as your other Adiuvo tools, with database-error detection switched on by default.
Competitor prices observed October 10, 2026. Site Monitor prices are current.
Choose Site Monitor when
- You already use Adiuvo and want monitoring, alerts and incident history on the same account.
- You want pages that load but show a database or application error treated as down, without setting up keyword checks.
- You prefer billing in Canadian dollars.
Choose an alternative when
- You only need uptime checks. Both free plans cost nothing, and UptimeRobot says its free plan allows commercial use.
- You watch many sites or need checks more often than every few minutes.
- You want SMS, phone or chat alerts and public status pages.

Outside the subscription
- Paid plans
- Both alternatives have free plans; their paid plans add faster checks, more monitors and team features.
- Currency
- UptimeRobot and Better Stack list prices in US dollars.
More on where Site Monitor fits
- A page that answers but shows a common database or application error is treated as down without extra setup.
- ADI access is included with the plan, but it is not counted as a saving.
Other trade-offs
- Alerts are by email to your alert contacts. SMS, phone and chat alerts are not part of the plans compared here.
- It checks that pages respond and certificates are valid. It does not test forms, logins or checkouts.
Switching and setup
- There is nothing to install: add the address of the page to check, choose the SSL warning, and add alert contacts.
