Comparison
Two of the most popular uptime monitoring tools. Here's how they compare.
UptimeRobot works well if you only need a handful of monitors. But once you grow past 50 monitors, pricing jumps quickly with their per-monitor model.
Pingdom brings enterprise features like RUM and transaction monitoring, but starts at $15/month for just 10 checks — and the price scales steeply from there.
If you need straightforward uptime monitoring without per-monitor limits, UptimeSignal gives you unlimited monitors for $15/month flat — the same price as Pingdom's most basic plan, with no caps. Free tier includes 25 monitors with no commercial-use restrictions.
UptimeSignal: 25 monitors free, unlimited for $15/month.
No monitor caps. No commercial-use restrictions. 1-minute checks. Status pages included.
