ExplainSQL

Visualize and interpret SQL execution plans with optimization recommendations

Code & DevelopmentFreemium

ExplainSQL takes raw EXPLAIN output from PostgreSQL, MySQL, or SQL Server and produces interactive visual diagrams showing data flow, cost breakdowns, and join strategies. Each node includes a plain-English explanation of the operation, estimated versus actual row counts, and specific recommendations for improving performance such as index creation, statistics updates, or query rewrites. Backend engineers use it to debug slow queries while database tutors use it to teach query optimization concepts visually.
