Most developers I've worked with write SQL every day. Very few of them are DBAs. According to the 2024 Stack Overflow Developer Survey — 65,000 developers across 185 countries — database administrators make up just 0.3% of the developer population. The tools built for SQL performance were designed for that 0.3%. I built QueryTuner for everyone else.I've spent 13 years as an application architect. In that time, I've watched the same situation repeat itself across teams: a query is slow, the developer who wrote it has to fix it, and the tools available to them are either way too expensive or way too generic. Enterprise monitoring agents like pganalyze or Datadog Database Monitoring cost hundreds of dollars a month and require installing an agent with full database credentials. Generic AI LLMs don't know whether you're on Oracle or MySQL. There's nothing useful in between.
