PEV2 is a web-based tool to visualize PostgreSQL execution plans. It takes EXPLAIN or EXPLAIN ANALYZE output and displays it in an interactive, tree-like format that highlights performance metrics, helping users understand query behavior and bottlenecks. PEV2 is a complete rewrite of the original PEV, offering a modern, user-friendly interface for query optimization.
Features
- Visualizes PostgreSQL execution plans in an interactive UI
- Supports both EXPLAIN and EXPLAIN ANALYZE output
- Highlights cost, timing, and row estimates
- Allows collapsing/expanding plan nodes
- Runs entirely in the browser without server dependencies
- Helps identify slow operations and optimize queries
