Detection Query Optimizer

Heuristic analyzer for KQL, SPL, Elastic, and Sigma queries. Catches performance anti-patterns, coverage gaps, and noisy filter patterns. Pastes go nowhere — analysis runs in your browser.

Input

Load: noisy KQL example Load: tuned KQL example Load: noisy SPL example Load: Sigma rule example
Heuristic analysis only. Tool catches common patterns; it does not parse query AST. Treat findings as a checklist, not a verdict.
