UptimeRobot

UptimeRobot is one of the world's most popular website monitoring services, trusted by over 2 million users to monitor more than 1.5 million websites and servers. Founded in 2010, UptimeRobot pioneered free uptime monitoring with a generous free tier that includes 50 monitors and 5-minute check intervals, making professional-grade uptime monitoring accessible to everyone from solo developers to large enterprises. The platform monitors HTTP(S), ping, port, and keyword endpoints from multiple global locations, sending instant alerts via email, SMS, Slack, webhooks, and 10+ other channels when downtime occurs. With its clean interface, powerful API, and public status page feature, UptimeRobot has become the go-to solution for ensuring website availability and maintaining customer trust.

What sets UptimeRobot apart is its simplicity combined with powerful features that scale from hobby projects to enterprise infrastructure. Unlike complex monitoring solutions requiring extensive setup, UptimeRobot lets you add monitors in seconds—simply enter a URL and start receiving uptime data immediately. The service checks your endpoints every 1-5 minutes depending on your plan, detecting downtime within seconds and sending alerts through your preferred channels. Public status pages let you communicate transparently with customers during incidents, while detailed uptime statistics, response time graphs, and downtime logs help you identify patterns and optimize performance. Whether you're monitoring a simple blog or managing hundreds of microservices, UptimeRobot provides reliable monitoring without the complexity or cost of enterprise solutions.
