About UptimeRobot

UptimeRobot is a commercial website monitoring service. It checks whether websites and services are reachable and notifies people when they are not, using alerts through email, SMS, Slack and other channels.

Monitor types include website and endpoint checks, keyword, ping, port, cron job, API and UDP monitoring, plus third-party service monitoring. Additional checks cover SSL, domain and DNS monitoring, with response-time tracking and multi-location checks. Incident management and public status pages are part of the product, and an API, a CLI, an MCP integration, other integrations and a mobile app extend it. Free tools such as an uptime calculator and a website change detector are offered. UptimeRobot is proprietary and vendor-hosted. A free plan is advertised, with paid tiers listed on its pricing page.
