Know the instant your website goes down — before your customers do — with 5-minute monitoring and instant multi-channel alerts.
UptimeRobot is a website and API monitoring service that checks your site every 5 minutes (free plan) or every 30-60 seconds (paid plans) from multiple global locations. When downtime is detected, it re-checks from multiple regions to confirm the outage, then sends instant alerts via email, SMS, voice calls, Slack, Discord, Microsoft Teams, or mobile push notifications. Includes SSL certificate and domain expiry monitoring, custom status pages for communicating incidents to customers, maintenance windows to suppress alerts during scheduled work, and API access for custom integrations. Free plan includes 50 monitors.
Website downtime detected within 5 minutes, instant alerts sent via email, SMS, Slack, or Discord, and a public status page created to communicate incidents to customers.
Developers, DevOps teams, marketers running paid campaigns, small business owners, and anyone whose revenue depends on their website being online.
Protect
Set up monitors for your homepage, checkout page, and any API endpoints immediately after signup. Configure at least two alert channels (email + Slack or Discord) so you never miss a notification. The SSL certificate monitoring is a hidden gem — it alerts you 30 days before your certificate expires, preventing the embarrassing "Not Secure" warning that kills conversions. Create a public status page before you need it — having one ready builds customer trust during incidents.
Operator notes document what it actually takes to get results, constraints, setup requirements, failure modes, and realistic expectations. This is the part most tool reviews skip.
