Slack alerts for downtime and missed crons
Downtime and missed cron runs land in the channel you already watch. Signed payloads, sub-5-second delivery, and retries when Slack hiccups.
// connect in minutes
01
Create an incoming webhook
Add an incoming webhook in your Slack workspace and copy the URL. One webhook per channel keeps routing obvious.
02
Paste it as an alert channel
Add the URL to any monitor or heartbeat. A test button fires a sample payload so you can confirm formatting before anything breaks.
03
Trust what arrives
Every delivery is HMAC-signed with retries and backoff, so a lost or forged alert is a non-event.
{
"event": "check.failed",
"check": "api-prod",
"region": "iad",
"signature": "hmac-sha256=9f2c"
} Unlimited Slack alerting on every plan, $19 flat, free during beta.
Frequently asked questions
Which Slack webhook type do I need?
A standard incoming webhook URL. Paste it as an alert channel. That is the whole setup, with no app review or OAuth dance.
How fast will I know when something breaks?
Checks run every 30 seconds from 6 regions, and three regions must agree before an alert fires. Fast, with no 3 a.m. false alarms.
Is it free during the beta?
Yes, everything is free during the beta, and waitlist members lock $19/mo forever at launch.
