Live monitoring

Polls pg_stat_statements every 30 seconds. Slow queries surface automatically with no instrumentation needed.

EXPLAIN analysis

Parses execution plans. Detects seq scans, missing indexes, hash joins, stale stats, and N+1 patterns.

Shadow DB testing

Benchmarks every recommendation on a real copy of your data before touching production.

AI-powered fixes

Claude explains root cause in plain English. Generates CREATE INDEX CONCURRENTLY migration SQL.

Index health

Finds unused, bloated, and duplicate indexes wasting disk space and slowing down writes.

CI/CD integration

REST endpoint catches slow queries before they reach production. GitHub Actions snippet included.
