Incident alerts
Get notified when monitors open or recover from incidents — with enough context to start investigating immediately.
- Email alerts on every plan when an incident opens or resolves.
- Paid plans: Slack incoming webhooks, HTTP webhooks, and device push.
- Alerts include likely failure layer, URL, and link to the monitor dashboard.
- No spam on every failed probe while an outage is still open.
