Updated October 2026
If you’re evaluating a SolarWinds DPA alternative for SQL Server, this comparison of AI SQL Tuner Studio and SolarWinds Database Performance Analyzer covers features, deployment, data handling and pricing side by side.
The short version: they’re different kinds of tools. DPA is a 24/7 monitoring platform for many database engines. AI SQL Tuner Studio is an on-demand tuning tool built only for SQL Server, which tells you what’s wrong and gives you the scripts to fix it.

Product Summaries
AI SQL Tuner Studio
AI SQL Tuner Studio is a Windows desktop application purpose-built for SQL Server performance tuning. You connect it to a server with a least-privileged login and pick one of six tuning goals. It collects the relevant diagnostics, such as wait statistics, Query Store and plan cache data, index usage, configuration and deadlock history, and has an AI reasoning model analyze them together. In about a minute you get a prioritized report with explanations and ready-to-run T-SQL.
It supports SQL Server 2016 and later in every edition, plus Azure SQL Database, Azure SQL Managed Instance and Fabric SQL Database. It sends diagnostic metadata to the AI model, never table data or query results, and analyses aren’t kept unless you opt in.
SolarWinds Database Performance Analyzer (DPA)
SolarWinds DPA is a server-based monitoring platform that watches databases continuously across SQL Server, Oracle, MySQL, MariaDB, SAP ASE, IBM Db2 and more, on-premises, virtualized and in the cloud. It uses wait-time analysis and machine learning to detect anomalies, surface slow queries and forecast resource needs. Its AI Query Assist feature explains slow queries in plain language and suggests improvements.
Feature-by-Feature Comparison
| Feature | AI SQL Tuner Studio | SolarWinds DPA |
|---|---|---|
| Primary use | On-demand SQL Server tuning: find the cause and get the fix | Continuous, real-time database monitoring across many engines |
| Database support | SQL Server 2016+ (all editions), Azure SQL Database, Azure SQL Managed Instance, Fabric SQL Database | SQL Server, Oracle, MySQL, MariaDB, SAP ASE, IBM Db2, cloud databases and more |
| Deployment | Windows desktop app; nothing installed on your servers | Self-managed server or SaaS; agentless, read-only collection |
| Monitoring | Point-in-time analysis when you run it | 24/7 monitoring with historical trends |
| AI | AI reasoning models (GPT-5.6 Luna, GPT-6 Sol) write each report, with prioritized findings and confidence levels | Machine learning anomaly detection; AI Query Assist explanations |
| Index analysis | Missing, duplicate, overlapping and unused indexes, with scripts and the storage each change adds or frees | Index recommendations from query analysis |
| Query analysis | Query Tuner: execution plan analysis, rewritten queries and index scripts | Wait-time drill-down per query, with execution plans |
| Code review | Code Review of stored procedures, functions, triggers and views, with replacement scripts | Query-level analysis; no dedicated code review |
| Deadlocks and blocking | Fix Deadlocks rewrites the code involved; Locking and Blocking Analysis explains live blocking | Blocking and deadlock detection with historical context |
| Server health | Server Health Check: configuration, waits, memory, storage, backups, security and patch level | Resource metrics and trends; anomaly alerts |
| Alerting | No; report-based | Yes; threshold and anomaly alerts |
| Dashboards | HTML reports you can save, share and export as SQL | Rich dashboards, trend charts and custom reports |
| Data handling | Diagnostic metadata goes to the AI model on Microsoft Foundry in Azure, or to your own endpoint; table data and query results never do; nothing kept by default | Performance data stored on your DPA server, or with SolarWinds for the SaaS option |
| Setup | Install, connect with a read-only login, run | Requires a DPA server or SaaS subscription and onboarding of each instance |
| Multi-server | Enterprise edition: unlimited server connections | Central management of many instances |

SolarWinds Database Performance Analyzer
DPA is licensed per monitored database instance, by subscription. Total cost depends on the number and type of instances and the deployment option, and for a fleet of instances it typically runs well into the thousands of dollars a year.

Who Should Use Each Tool?
AI SQL Tuner Studio is a strong fit if you…
- Run SQL Server, Azure SQL Database, Azure SQL Managed Instance or Fabric SQL Database
- Want to know why something is slow and get the fix: index scripts with storage sizes, rewritten queries, replacement procedures and deadlock fixes
- Want results in minutes without deploying monitoring infrastructure
- Need to keep table data and query results out of any external service
- Are a DBA, developer, consultant or small team watching costs
SolarWinds DPA is a strong fit if you…
- Manage many database engines, such as Oracle, MySQL and SQL Server, from one place
- Need 24/7 monitoring with real-time alerts and historical trends
- Want enterprise dashboards and central management across a large fleet
- Have the budget and team for a monitoring platform
Summary
These tools serve different purposes. SolarWinds DPA watches your databases all the time and tells you when and where performance changes. AI SQL Tuner Studio is what you open when you need to understand a SQL Server problem and fix it, with prioritized recommendations and ready-to-run scripts, from $0 to $20 a month.
For SQL Server teams that don’t need round-the-clock monitoring, AI SQL Tuner Studio delivers deep analysis at a small fraction of a monitoring platform’s cost. For mixed-engine fleets with strict uptime SLAs, DPA’s continuous coverage and alerting are something an on-demand tool doesn’t replace. Teams can use both.
Frequently Asked Questions
Does AI SQL Tuner Studio support databases other than SQL Server?
No. It’s purpose-built for the Microsoft SQL platform: SQL Server 2016 and later in every edition, Azure SQL Database, Azure SQL Managed Instance (General Purpose and Business Critical) and Fabric SQL Database. It doesn’t support Oracle, MySQL or other engines.
Does SolarWinds DPA include AI features?
Yes. DPA’s AI Query Assist uses generative AI to explain slow SQL statements in plain language and suggest improvements, and DPA uses machine learning for anomaly detection and forecasting.
Is my data sent to the cloud with AI SQL Tuner Studio?
Studio sends diagnostic metadata, such as query text, execution plans, index statistics and configuration, to the AI model hosted on Microsoft Foundry in Azure. It never sends table data or query results, and analyses aren’t kept unless you opt in. You see a run plan of everything it will collect before each run, and on paid editions you can use your own AI endpoint instead.
How does AI SQL Tuner Studio pricing compare to SolarWinds DPA?
AI SQL Tuner Studio is $0 for the Free edition and $10 to $20 a month for paid editions. DPA is licensed per monitored instance by subscription, so its cost grows with the size of your fleet; check SolarWinds for a current quote.
Can both tools be used together?
Yes. Teams can use DPA for continuous monitoring and alerting across their fleet, and AI SQL Tuner Studio for in-depth SQL Server analysis, code review and fixes when DPA flags a problem.
