Slack app
Run incident response from Slack
Alerts landing in a channel is table stakes. The Alertum app works both ways: acknowledge and resolve incidents, pause monitors during deploys, check who's on call, and open maintenance windows — without switching tabs.

Frequently asked questions
Do I need an Alertum account first?
No — installing to Slack is the account creation. Click “Add to Slack,” choose your workspace, and Alertum resolves or creates your account automatically, the same way “Sign in with Google” works.
Can the app take actions, or does it only send alerts?
Both. It posts incident and monitor alerts to channels you pick, and your team can acknowledge, resolve, pause, resume, and manage maintenance windows directly from Slack commands.
Which channel do alerts go to?
You choose per monitor when you set it up (via /alertum monitor or the dashboard) — alerts aren't broadcast to every channel by default.
Can I remove the app later?
Yes — remove it from Slack's App Directory management page, or disconnect the workspace from Alertum's integration settings. Both revoke access immediately.
