About
From the App Store SourceQuerycairn is a private query-plan interpretation bench for developers, database administrators, consultants, and technical teams who need a focused second screen without pasting schema or plans into a website. Surface the nodes where row-estimate error and loop amplification make a seemingly small plan expensive. KEY FEATURES - PostgreSQL EXPLAIN JSON import - Recursive plan-node inventory - Estimated-versus-actual row view - Loop and predicate risk scoring - Node owner and hypothesis notes - Statistics and index checklist - Plan findings export - Database credentials never requested - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - No account, ads, analytics, tracking, IAP, or subscription Querycairn interprets recorded PostgreSQL plan fields and entered context; it does not connect to a database, execute SQL, recommend an index automatically, or prove a change is safe. EXPLAIN ANALYZE executes the statement. Use controlled data, representative parameters, and expert review.
