PlanScope

PlanScope turns a raw Postgres EXPLAIN ANALYZE output into a plan you can actually read.

Paste in a plan and PlanScope renders it as a tree, ranks every node by how much time it actually spent (not just how the planner guessed), and highlights the slowest operations with a heatmap — so the one join or seq scan that's dragging down your query jumps out immediately instead of hiding in a wall of text.

PlanScope also flags planner row-estimate mismatches — one of the most common real-world causes of a bad query plan — by comparing estimated rows against actual rows at every node.

Save plans as you go and search back through your history later, whether you're chasing down the same slow endpoint again or comparing before/after a schema change.

Fully local — nothing is sent anywhere. Paste your plan text and PlanScope does the rest, offline.

Free: save up to a handful of recent plans. Pro (one-time unlock): unlimited saved plans, plus side-by-side comparison of two plans at once.
