Show HN: Nightwatch, The open-source, read-only AI SRE

Nightwatch is an open-source, read-only AI SRE tool designed to enhance monitoring systems by grouping alert storms into incidents, flagging noisy checks, and using an agent to investigate live systems. Developed after a Kubernetes upgrade incident, it emphasizes local-first deployment, self-hosting, and data security through masked secrets during remote LLM interactions.
