PostgreSQL tools that run in your browser

Small, fast, free utilities for developers who work with PostgreSQL every day.

🔒 Nothing is uploaded. All parsing and analysis happens client-side in your browser. Your query plans, queries and data never reach any server.

EXPLAIN ANALYZE Visualizer

Paste the JSON output of EXPLAIN (ANALYZE, FORMAT JSON) and get an interactive plan tree: per-node timing bars, row-estimate mismatches, disk spills and other common performance problems highlighted automatically.

Why these tools?

Reading a raw PostgreSQL query plan is hard: timings are cumulative, row counts are per-loop averages, and the interesting problems (bad estimates, sorts spilling to disk, expensive nested loops) hide in the details. These tools do the arithmetic for you and point at what actually matters.

More tools are coming: pages explaining common PostgreSQL errors, a postgresql.conf generator, and an index size calculator.
