Alerts

Deep Dive

The outage and the all-clear

A closer look at what you get, from the first check to the alert that reaches you.

Send downtime and recovery notifications to any address.

Native webhook integrations post rich, readable alerts directly to your channels.

Send signed JSON payloads to any endpoint, with an HMAC signature header.

Get notified when a service comes back up, including downtime duration.

Set a minimum time between repeat alerts so an ongoing outage doesn't flood your inbox.

Route some alerts to the whole team and others to a single critical monitor.

FAQ

The questions people ask most before they start monitoring.

Which alert channels are supported?

Email, Slack, Discord, and generic webhooks — connect to any other service via webhook.

What happens when an outage is detected?

Uptime immediately sends an alert through every configured channel for that monitor.

Can I avoid getting alerted repeatedly during a long outage?

Yes — set a cooldown so the same alert only re-fires after a minimum time has passed.

Do webhook payloads carry a signature?

Yes. Set a secret and every webhook request includes an HMAC SHA-256 `Webhook-Signature` header.

Create your first monitor in under 2 minutes. No credit card required to start.
