# OpenCluster

> Investigate incidents across the systems you already use, with cited findings and read-only access.

OpenCluster investigates alerts across your operational systems. It connects to your
existing alerting, infrastructure, collaboration, and source-control tools. When an
incident needs attention, it follows the useful signals, records each read, and returns
findings you can audit.

Alertmanager starts the incident. Connected systems such as Slack and GitHub provide
context when they are relevant. OpenCluster does not replace those systems or require a
new telemetry pipeline.
