Show HN: AI SRE Arena, an open benchmark for AI SRE agents on Kubernetes

AI SRE Arena is an open, vendor-neutral benchmark that injects faults into a disposable Kubernetes fixture and scores AI SRE investigations with a configurable judge.

In its first published comparison across 21 incident scenarios, Edge Delta's native AI investigations detected 18 of 21 incidents, and Grafana's detected 12.

Claude, run through each vendor's observability CLI, reached 90.5% root cause analysis accuracy with Grafana's CLI and 85.7% with Edge Delta's.
