Which Edition Is Right for You?
Choosing the right AI SQL Tuner Studio edition depends on your SQL Server environment and team requirements. If you are learning SQL Server or developing on a local Developer Edition instance, the Free edition gives you everything you need. For small teams running Standard Edition or Azure SQL Database in production, the Standard edition covers those platforms at the lowest cost. If your organization relies on SQL Server Enterprise Edition or Managed Instance Business Critical, the Pro edition provides the necessary compatibility.
If you manage a large number of servers across your organization, the Corporate edition removes the server connection limit entirely. Use the table above to compare AI SQL Tuner Studio editions and find the best fit for your infrastructure. You can also start a 14-day free trial to compare AI SQL Tuner Studio editions hands-on before committing.
All editions run locally on your Windows desktop — no data is stored in the cloud. Your SQL Server metadata stays on your machine. You can bring your own Azure OpenAI endpoint or use the managed endpoint provided by AI SQL Tuner LLC. For setup details, see the AI SQL Tuner Studio User Guide.
