$2.99
Analyze slow SQL queries — suggest indexes, rewrite queries, and detect N+1 problems in ORMs.
Takes SQL queries (PostgreSQL, MySQL, SQLite) or ORM code (Prisma, TypeORM, SQLAlchemy, ActiveRecord) and identifies performance issues: missing indexes, sequential scans, N+1 queries, inefficient joins, and suboptimal WHERE clauses. Suggests EXPLAIN ANALYZE interpretation, index creation DDL, query rewrites, and ORM eager-loading fixes. Estimates performance improvement for each fix.
