QueryPlan

Visualize and optimize SQL query execution plans with cost breakdown

Code & DevelopmentFree

QueryPlan takes SQL queries and their database execution plans and renders interactive visual diagrams showing the flow of data through each operation with actual vs estimated row counts, I/O costs, memory usage, and time spent at each node. The tool highlights operations that are disproportionately expensive and suggests index additions, query rewrites, or schema changes that could improve performance. Database developers use it to understand why specific queries are slow while performance engineers use it to prioritize optimization efforts across a workload of many queries.
