Read-only Kubernetes audit that runs from your laptop. One reading lists reliability, security and cost findings from 89 detection rules and 15 stack analyzers, each tied to its object. Preflight answers a change before you make it: which node won't drain, what a lost zone strands, what blocks the next upgrade. CI/CD gate with SARIF, findings filed in Jira or Linear. Free preflight; CLI and desktop app for macOS, Windows and Linux.
