See what UptimeRobot costs, how its uptime and SSL monitoring works, and whether its free plan and paid tiers fit your team.
UptimeRobot is a cloud-based monitoring service that continuously checks whether websites, APIs, servers, and other endpoints are online and performing correctly. Founded in 2010 and now owned by Pale Fire Capital, it has grown into one of the most widely used uptime monitoring tools, watching millions of monitors for individual developers, agencies, and larger engineering teams.
The service works by pinging a target URL, port, or keyword from multiple locations around the world on a set interval, then firing alerts the moment a check fails so a false positive from a single region does not trigger unnecessary noise. Beyond basic up/down checks, it also tracks SSL certificate and domain expiration dates, response times, and DNS record changes.
UptimeRobot supports HTTP/HTTPS, ping, port, keyword, cron job, DNS, SSL, and UDP monitoring, with multi-location checks to reduce false alarms. Alerting covers email, SMS, voice calls, mobile push notifications, and more than a dozen integrations such as Slack, Microsoft Teams, Discord, and PagerDuty.
Customers can build branded, password-protectable public status pages to communicate incidents to their own users, and collaborate on incidents internally with notes and timelines. Maintenance windows let teams silence alerts during planned downtime, and role-based access controls govern who on a team can view or edit monitors.
UptimeRobot's Free plan includes 50 monitors checked every 5 minutes with 3 months of data retention, making it usable for personal projects and small sites without a credit card. Paid plans, Solo, Team, and Enterprise, drop the check interval to 60 seconds (30 seconds on Enterprise), add more monitors, longer retention, more status pages, and team seats, starting at roughly 10 euro per month and scaling up based on monitor count and features like SOC 2 and GDPR compliance on Enterprise.
SMS and voice alert credits are sold separately as one-time top-ups, and all paid subscriptions come with a 14-day money-back guarantee.
