Querycairn: Explain Plans
软件开发工具
¥8.00 · 专为 iPad 设计。未针对 macOS 验证。
Querycairn 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.
