PostgreSQL Query Plan Visualizer

Paste an EXPLAIN plan below and see it as a diagram — free, in your browser, no signup.

Every query passes through the parser, rewriter, and planner before the executor runs the chosen plan — EXPLAIN shows you that plan directly.

Query execution pipeline: Parser, Rewriter, Planner (Optimizer), Executor
The planner uses table statistics (pg_stats) to choose the plan EXPLAIN shows you.
