SQLFlash vs SupaSQL

SQLFlash rewrites slow queries, recommends indexes, and explains every change in plain language. You paste a statement or upload a MyBatis XML mapping, and it returns an optimized version with a diff viewer, query plan breakdown, and performance score. It supports MySQL, PostgreSQL, Oracle, SQL Server, MariaDB, TiDB, and other relational engines without needing database credentials.

Most SQL tuners either need live access to your database or hand you a rewritten query with no context. SQLFlash takes the opposite approach: it works on the text alone, uses a two-stage rule filter to match optimization patterns, and documents each rewrite step in a journal you can audit. That trade-off means you validate results in your own test environment, but you never grant read access to production data.

Developers, DBAs, and platform teams use SQLFlash when legacy queries slow down apps, when MyBatis XML files pile up without review, or when a database migration changes execution plans overnight. Case studies on the site cover e-commerce product pages, banking dashboards, restaurant order history, and school course progress queries.
