Companion to Prometheus that routes, groups, deduplicates, and silences alerts and dispatches them to email, Slack, PagerDuty, and more.
Version
The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
