Get notified the moment something breaks
Instant Email and Slack alerts whenever a monitor goes down or comes back up. Customise the message with your own templates and dynamic placeholders.
Everything you need
Purpose-built features that make real-time alerts reliable, fast, and easy to act on.
Email & Slack
Send downtime alerts to email inboxes and Slack channels simultaneously. Multiple destinations per channel.
Sub-second dispatch
Alerts go out within seconds of confirming an outage — not minutes. Every second counts during an incident.
Custom templates
Use dynamic placeholders like {{monitor_name}}, {{url}}, {{error}}, and {{down_since}} to craft perfect alert messages.
Full alert history
See every alert ever sent — when it fired, which monitor triggered it, and the full notification details.
How it works
Up and running in 60 seconds — no code required.
Connect your channels
Add email addresses and Slack webhook URLs in your alert settings. Add multiple destinations per channel.
Customise your templates
Edit the subject and body of down/recovery alerts with dynamic placeholders that fill in real data at send time.
