About this tool
Postgres, SQLite, and MySQL overlap but are not interchangeable. This page lays out the real tradeoffs — concurrency, ops, cost, extensions — in plain language, then scores your answers against typical fit patterns.
It is not a benchmark. Your query patterns, team skills, and hosting constraints matter more than generic rankings. When you are choosing between database categories (relational vs KV vs columnar), use the Database Chooser instead.
