SQLFlash

SQLFlash is an AI-assisted tool for automatically optimizing SQL queries. It helps teams spot performance bottlenecks, rewrite inefficient queries, and choose better indexes without time-consuming manual trial and error.

Faster query optimization with clear explanations

Paste a SQL query to get an improved version along with reasoning behind the changes. SQLFlash supports complex patterns and highlights what impacts execution speed.

• Query rewriting for inefficient SQL
• Support for dynamic queries, complex joins, and subqueries
• Explanations of how each change affects performance

Execution plan and index recommendations

SQLFlash reviews execution plans to identify costly operations and suggests practical fixes that engineers and analysts can apply.

• Detects full table scans, unused indexes, and unnecessary sorts
• Recommends indexes and query structure changes based on plan analysis

Database support and data safety

SQLFlash works with major relational databases, including MySQL and PostgreSQL. It does not require access to confidential business data—only the queries and metadata—making it easier to adopt in security-conscious environments.

• Uses queries and metadata instead of sensitive data
• Helps teams spend less time on SQL tuning and more on product logic
