UptimeRobot: Pricing, Features & Alternatives

UptimeRobot has been the default free uptime checker for over a decade. It covers HTTP, keyword, ping, port, SSL and cron heartbeat monitors, with alerts to email, Slack and a long list of integrations, and it publishes status pages from the same data. The free plan runs 50 monitors at 5-minute intervals with one status page. Paid plans are about faster checks and more pages. Solo is $10/month ($9 billed annually), but that buys 60-second checks on 10 monitors, fewer than the free plan. Team is $41 for 100 monitors at 30 seconds, and Scale is $77 for 15-second checks.
