QueryGuard | SQL Optimization Auditor

How it helps

Use it for a focused task

QueryGuard provides an interactive pre-flight checklist for developers merging database queries, covering index usage, function sargability, and aggregation costs. Select your target database engine.

Paste your SQL query into the local scratchpad. Walk through the logic checks.

Once verified, copy the auto-generated markdown report to attach to your pull request. Catches catastrophic but common SQL patterns (like implicit casting or full table scans) before they reach production servers and cause performance degradation.
