Canary9 vs UptimeRobot

- Slack and webhook alerts on every plan, including Free
- Multiple test regions from the $15 Pro plan
- Flat three-tier pricing instead of monitor-count brackets
UptimeRobot is better for

- SMS and voice alerting via prepaid credit packs
- Faster top-end intervals: 30 s on Team, 15 s on Scale

Cost analysis by scenario
UptimeRobot sells monitor-count and interval tiers: free 5-minute checks, then Solo, Team, and Scale unlock 60-, 30-, and 15-second intervals with larger monitor brackets. Estimates use annually billed effective rates and price each scenario at the cheapest tier that covers it.
Five basic uptime checks
5 HTTP endpoints at a 5-minute interval
Production uptime checks
10 HTTP endpoints at a 1-minute interval
API and browser monitoring
10 API checks and 10 browser checks
How UptimeRobot pricing works
Free includes 50 monitors at a fixed 5-minute interval. Solo starts at $11 per month billed annually ($13 monthly) for 10 monitors at 60 seconds; Team ($32 annually) reaches 30 seconds and adds webhooks and PagerDuty; Scale ($70 annually) reaches 15 seconds.
Slack requires Solo or higher; webhooks and PagerDuty require Team or higher. The free plan is limited to a handful of integrations and has no login or notify seats.
SMS and voice alerts use one-time credit packs, from $3 for 10 credits to $100 for 1,000. Credits do not renew monthly and consumption varies by destination country.
USD before tax; annual billing where a choice exists; prices read from UptimeRobot's published pricing page. Browser transaction checks are unavailable at any tier, so the third scenario has no UptimeRobot price.
