Question 1

How do I optimize a slow SQL query?

Accepted Answer

Paste your SQL query into SQL Optimizer. Our AI analyzes it for missing indexes, full table scans, inefficient joins, and N+1 problems, then produces an optimized rewrite.

Question 2

What is EXPLAIN ANALYZE in PostgreSQL?

Accepted Answer

EXPLAIN ANALYZE executes the query and returns the actual execution plan with per-node timing and row counts. SQL Optimizer visualizes this output to pinpoint bottlenecks and suggest CREATE INDEX statements.

Question 3

Is this SQL formatter free?

Accepted Answer

Yes. SQL Optimizer is completely free to use. Paste any query and get instant formatting, explanation, and AI-driven performance improvements.
