UptimeRobot
Free website and service monitoring with status pages.
UptimeRobot is a hosted monitoring service that repeatedly checks websites, APIs, servers, and other endpoints, raising alerts when something is down, degraded, or changed. It also provides status pages for publishing service health and incident updates.
Features include HTTP/HTTPS, keyword, ping, port, cron/heartbeat, DNS, SSL certificate, domain expiry, UDP, and API monitoring, with multi-location checks and response-time alerts. Alerts can be sent via email, SMS, voice call, mobile push, and integrations such as Slack, Microsoft Teams, PagerDuty, Zapier, and webhooks. Status pages support custom domains, branding, password protection, and incident history. Role-based team access, maintenance windows, incident management tools, and API access are also available.
UptimeRobot is aimed at freelancers, small teams, and larger organizations monitoring production services. It offers a free plan with 50 monitors and 5-minute intervals, plus paid Solo, Team, and Scale editions with shorter intervals, more monitors, seats, and status page features. An Enterprise edition adds custom intervals, compliance documentation, dedicated support, and custom invoicing.
