Frequently Asked Questions
Is UptimeRobot really free for 50 monitors?
Yes, the free plan includes up to 50 monitors with 1-minute check intervals, basic status pages, and email/push notifications. No credit card is required, but paid features like SMS alerts and 30-second checks are not included.
What types of things can I monitor besides website uptime?
You can monitor HTTP/HTTPS endpoints, keywords, ping, ports/TCP services, DNS, and SSL certificate expiration. This covers public websites, API endpoints, and basic network services without requiring a dedicated agent.
Does UptimeRobot work with Slack, Teams, or PagerDuty?
Yes, UptimeRobot supports email, SMS, voice calls, Slack, Microsoft Teams, Discord, webhooks, Zapier, PagerDuty, and several other integrations. Some notification channels, especially SMS and voice, require paid credits or higher plans.
Can I create a public status page on the free plan?
Yes, free accounts can create a status page and add monitors to it. You can customize basics like logo, colors, and public/private access, but advanced customization and custom domains may require a paid plan.
How quickly will I be alerted if my site goes down?
Free monitors run every 1 minute, so alerts can arrive within a couple of minutes of an outage. Paid plans offer 30-second intervals for faster detection, and delivery time also depends on your alert channel.
Can UptimeRobot monitor SSL certificate expiration?
Yes, UptimeRobot can check SSL certificates and send alerts before they expire. These are counted as monitors, so they consume one of your monitor slots.
