EverSQL automatically optimizes MySQL and PostgreSQL queries with AI, cutting query time and cost; free to use and now part of Aiven's data platform.
EverSQL is a database performance tool that uses AI to analyze SQL queries running against MySQL or PostgreSQL databases and automatically suggest or apply optimizations, such as rewriting inefficient queries and recommending new or removed indexes. It grew out of a common problem for backend teams: as an application scales, certain queries become slow, and manually finding the cause requires specialized database expertise that many engineering teams don't have readily available.
In November 2023, EverSQL was acquired by Aiven, an open-source cloud data platform company, and its optimization engine has since been folded into Aiven's broader tooling while remaining accessible as a tool developers can use for free, both on its original eversql.com domain and through Aiven's own site.
The core of EverSQL is its AI query optimizer, which takes a slow SQL query as input and returns a rewritten, faster version along with an explanation of what changed and why, covering things like join order, subquery restructuring, and index usage. A companion database monitoring sensor can be installed non-intrusively to continuously observe real query performance in production and surface which specific queries are worth optimizing.
EverSQL also looks at overall schema and index health, flagging redundant or unused indexes that add write overhead without improving read performance, which can reduce both query latency and infrastructure cost. The company reports that its customers see substantial time savings, citing an average query speedup of about 25 times for the queries it optimizes.
EverSQL is offered as a free tool for query optimization, positioned by Aiven as a way to demonstrate the value of good database tuning and, by extension, Aiven's broader managed database and data platform offerings.
There is no separate paid tier specifically for EverSQL's core optimizer; instead, deeper database monitoring, hosting, and management capabilities are available through Aiven's own paid managed database services, which EverSQL now effectively serves as an entry point into.
No, EverSQL was acquired by Aiven, a cloud data platform company, in November 2023, and now operates as a free tool within Aiven's broader offering.
EverSQL's query optimization tool is free to use.
EverSQL supports MySQL and PostgreSQL.
It uses AI to analyze and rewrite slow SQL queries and recommends index changes, and it can monitor live production databases to identify which queries need attention.
No, EverSQL is designed to give developers actionable optimization suggestions without requiring deep database administration expertise.
