PlanScope
Postgres EXPLAIN Visualizer
Only for Mac
Free · In‑App Purchases
Mac
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.
— WHAT MAKES PLANSCOPE DIFFERENT —
• Ranks nodes by real actual-time, not just what the planner predicted
• Row-estimate mismatch detection catches a leading real-world cause of bad plans
• Searchable plan history for comparing before/after a schema change
• Fully local — nothing is sent anywhere, paste and PlanScope does the rest offline
— PRICING —
PlanScope saves your 5 most recent plans. Pro is a one-time purchase (no subscription) that removes that limit, so your whole searchable plan history stays in the app.
