Catch downtime before your customers do.
NotifyUp watches your sites around the clock and alerts your team over email, SMS, voice call, and Slack the moment something breaks — with response-time and SSL insight to fix it fast.
Everything you need to stay ahead of downtime
Comprehensive monitoring and alerting built to keep your sites fast, secure, and always online.
Reliable monitoring
Checks as often as every minute, 24/7. Every failure is re-checked before an incident opens — so you're alerted to real outages, not blips.
Response-time tracking
Track latency over time, spot slowdowns early, and pinpoint exactly when they start.
Multi-channel alerts
Route incidents to email, SMS, voice call, and Slack — with alert delays and repeat reminders until someone responds.
Content & status checks
Assert the exact status code and require (or forbid) a keyword in the response — so a page that returns 200 while showing an error still counts as down.
Analytics & incidents
Uptime reports, response-time trends, and 90 days of incident history to spot patterns and prove your reliability.
SSL certificate monitoring
Get warned well before certificates expire, with automatic health checks on every domain you monitor.
Get notified your way
Choose the channels that fit your team. Every incident reaches the right people, fast.
Email alerts
Instant, detailed incident emails with the exact error and how long the site has been down.
SMS alerts
Critical text messages for the incidents that can't wait for someone to check their inbox.
Voice call alerts
An automated phone call that reads the outage aloud — impossible to sleep through when it matters most.
