# SQL Visual Optimizer

> SQL Visual Optimizer — Interactive Query Planning, Cost Analysis, and SQL Performance Laboratory.

SQL Visual Optimizer is a browser-first research and educational software application created by Faramarz Kowsari. It parses SQL, displays abstract syntax trees, creates transparent estimated logical plans, imports PostgreSQL-compatible EXPLAIN JSON, identifies common SQL anti-patterns, and proposes exploratory index hypotheses.
