UptimeRobot Monitoring Service

UptimeRobot is a website and service monitoring platform that checks the availability of web endpoints every 30 seconds to 5 minutes and alerts users immediately when downtime is detected. Founded in 2010, the service monitors over 2 million endpoints for more than 400,000 users worldwide, including developers, agencies, and enterprises. The free plan supports 50 monitors with 5 minute check intervals, while paid plans offer up to 1 minute intervals, more monitors, and advanced features. Monitor types include HTTP and HTTPS website monitoring, keyword monitoring that checks for the presence or absence of specific text on a page, ping monitoring for server availability, port monitoring for TCP services like SMTP, FTP, DNS, and custom ports, and cron job monitoring that expects periodic heartbeat pings. Alert channels include email, SMS, voice calls, Slack, Discord, Telegram, Microsoft Teams, Pushover, PagerDuty, and custom webhooks. The platform maintains a public status page feature with custom branding, allowing teams to share real time availability information with stakeholders. The API enables programmatic monitor management, and the dashboard provides uptime percentages, response time charts, and incident history. Multi step monitoring and maintenance windows prevent false alerts during planned downtime.
