Slack uptime and downtime alerts

Send an alert to Slack the moment a website, API, server or cron job goes down, and again when it recovers.

Down, back up and SSL alerts

Slack hears when a monitor goes down, when it recovers (with how long it was down) and before a certificate expires.

Only real outages

Every failure is retried and confirmed from California, Amsterdam and Singapore before anyone is alerted, so network blips stay quiet.

The reason, not just “down”

Each alert says what failed, such as HTTP 503, a timeout or a missing keyword, how many regions saw it, and links to the monitor.

Set it up

  1. 1In Slack, create an app with an Incoming Webhook for the channel you want alerts in, and copy its URL.
  2. 2In Spot Downtime, open Alerts → Add channel → Slack and paste the webhook URL.
  3. 3Click Send test to check it arrives. Alert channels are on every plan, including Free.

Free for your whole team

20 monitors, checks from three regions and every integration on the Free plan. No card needed.
