About UptimeRobot

UptimeRobot is a monitoring platform that checks websites, servers, ports, APIs, and SSL certificates at regular intervals (as frequently as every 30 seconds on paid plans) and alerts users the moment something goes down. It supports multiple monitor types — HTTP(s), ping, port, keyword-based, and heartbeat monitoring for cron jobs and background processes — with alerts delivered via email, SMS, voice call, Slack, Microsoft Teams, Discord, or webhooks. Public and private status pages let teams communicate uptime and incidents transparently to customers or stakeholders, while maintenance windows allow scheduled downtime without triggering false alerts. UptimeRobot offers a free plan covering up to 50 monitors at 5-minute intervals, making it accessible for small projects, with paid tiers unlocking faster check intervals, more monitors, and advanced features like response time tracking and multi-location checks. It's built for developers, agencies, and businesses that need to know immediately when a website, API, or server goes offline rather than finding out from a customer complaint.
