UptimeRobot is an uptime-monitoring service that checks websites, APIs and other endpoints and alerts you when something goes down, slows down or changes. It offers HTTP(S), keyword, ping and port checks, cron-job and heartbeat monitoring, and monitoring of SSL certificates and domain expiry. Alerts are sent by email, SMS, voice call, app push and integrations such as Slack, Teams and PagerDuty. UptimeRobot also provides public status pages with custom domains and maintenance windows. The service is delivered as SaaS and is not open source.
UptimeRobot is operated by UptimeRobot s. r. o. in Bratislava, Slovakia, and is part of the itrinity portfolio. According to its privacy policy, the monitoring infrastructure and status pages run at Hetzner, while Amazon Web Services, DigitalOcean, Limestone Networks, Cloudflare, Vercel and other providers are used for checks, storage, DNS and the dashboard. Data may also be processed outside the EEA, with appropriate safeguards. A European organisation should therefore check which data goes to which sub-processor.
