OptimizeQL — AI-powered SQL query optimizer

Go library and CLI to parse PostgreSQL EXPLAIN (ANALYZE, FORMAT JSON) output and surface actionable performance findings

PostgreSQL queries from basic joins to window functions, recursive CTEs and measured index optimisation. One e-commerce schema, one Docker command, pure SQL.

PostgreSQL slow query watcher, tails auto_explain log output and reports actionable findings using pgexplain

Read PostgreSQL EXPLAIN plans locally: parse, compute self time and estimation error, flag documented problems, compare plans, and guard them in CI. No database connection, deterministic.

Turn PostgreSQL EXPLAIN output into human-readable reports and catch query-plan anti-patterns — every finding tells you exactly how to fix it.

Benchmark common SQL performance patterns on PostgreSQL: warm-up, median timings and the EXPLAIN ANALYZE behind every result

See the SQL your SQLAlchemy 2.0 statements really run, then read the EXPLAIN ANALYZE plan in plain English — seq scans, stale-stats row mismatches, disk sorts, and expensive nested loops annotated with fixes.

Turns PostgreSQL EXPLAIN (ANALYZE, BUFFERS) output into a readable plan tree in your terminal — finds the slow node without leaving the shell.

Native desktop tool for SQL execution-plan visualization and analysis. Supports PostgreSQL, MySQL, MariaDB, and SQLite.

PostgreSQL query performance tuning with EXPLAIN ANALYZE, BUFFERS, indexes, joins, materialized views, and correctness verification.

Production-grade guides and runbooks for query plan baseline tracking, performance regression detection, and CI/CD gate automation — for database SREs and platform teams.

Advanced SQL analytics on 20.6K Spotify/YouTube tracks (PostgreSQL): schema design, data-quality cleaning, 15 queries from aggregation to window functions & CTEs, plus EXPLAIN ANALYZE query optimization with B-tree indexing.

CLI wrapper around pev2 for visualizing PostgreSQL EXPLAIN plans with live reload

Eight realistic PostgreSQL performance problems, the fix for each, and harness-generated EXPLAIN ANALYZE evidence that the fix worked.

Paste an EXPLAIN ANALYZE plan, get an interactive tree with a self-time heatmap and diagnostics. Runs entirely in the browser.

Visual EXPLAIN ANALYZE breakdown for PostGIS queries, with GiST/SP-GiST/BRIN index suggestions and spatial rewrite hints. Zero-dependency static web app.

Evidence-first PostgreSQL plan analysis with deterministic diagnostics, workload regression checks, and grounded AI/RAG

Read a Postgres query plan in plain English. Paste EXPLAIN ANALYZE, find out what is actually slow and why. Runs entirely in your browser.

Local-first Postgres slow-query triage with Gemma 4 E4B. Plans never leave the machine. Built for the Gemma 4 Challenge.
