Uptime Monitoring Tools Compared: 2026

Your site goes down at 3 AM. Who tells you first — and at what cost?

We monitored 5 services (mix of static sites, APIs, and DB-backed apps) for 90 days using three tools. Each tool checked from 30+ global locations every 60 seconds.

TL;DR

| Use case | Pick | |----------|------| | Solo founder, 1-3 sites | UptimeRobot | | Bootstrapped SaaS | Better Uptime | | Agency managing client sites | Hetrixtools | | Enterprise | PagerDuty + Pingdom |

Detection Speed

We introduced 5-minute outages and measured time-to-alert:

| Tool | Median Alert | False Positives | |------|--------------|------------------| | UptimeRobot | 73 seconds | 2 (out of 28) | | Better Uptime | 52 seconds | 1 | | Hetrixtools | 89 seconds | 3 |

Better Uptime wins detection (30s default check interval).
