Querycairn: Explain Plans

iOS app by Shadowfetch · App Store ID 6792557968 · iOS

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.

Get it. Querycairn: Explain Plans is on the App Store for iPhone and iPad.
