EverSQL (now part of Aiven) is the leading AI-powered SQL optimization platform serving 100,000+ professionals. The platform provides automated query rewriting, index recommendations, and performance monitoring. Pricing tiers: Free (1 optimization/month), Starter ($79-129/month for up to 500 optimizations), and Enterprise ($1,799+/month for unlimited optimizations and advanced features). Supports MySQL, PostgreSQL, MariaDB, Amazon Aurora, and Percona with Oracle and SQL Server in beta. Key capabilities include automatic query rewriting that preserves semantic equivalence while improving performance, missing index identification with CREATE INDEX statements, slow query identification via Performance Sensor, and execution plan analysis.
