← Uptime Monitoring Pricing Calculator
Put your monitor count, check interval and status-page need into the calculator to price UptimeRobot, Better Stack, Hyperping, Pingdom and self-hosted Uptime Kuma side by side. These are the questions to settle before you trust the answer.
Plans are tiers, not per-unit prices. UptimeRobot's free plan covers 50 monitors at five-minute checks, but 60-second checks need a paid tier, and past 100 monitors you jump to the next one. Better Stack adds a per-monitor fee after its included monitors, while Pingdom steps through fixed 10, 50, 100 and 500-check plans. The cheapest provider at 10 monitors is rarely the cheapest at 120, which is what the crossover table shows.
Match it to how long an outage may go unnoticed. A five-minute check can miss a four-minute outage entirely and delays the alert by up to five minutes; 60 seconds is the usual paid default and 30 seconds or faster costs the most. If your SLA promises 99.9 percent monthly (about 43 minutes of downtime), a 3 or 5 minute interval is usually fine; for payment or login flows pay for 60 seconds or less.
It is free software and a small VPS runs hundreds of monitors, so it is cheapest on paper. The catches: the monitor must not live on the infrastructure it watches, you maintain and patch it, and you need a second independent way to alert you when the monitor itself dies. Many teams self-host for volume and keep one hosted monitor watching the self-hosted one.
