Query Performance Investigator

A clearer way to review SQL Server query-performance evidence.

QPI is an early-access product direction for teams that need to make sense of execution plans, Query Store evidence, regressions, and repeatable investigation workflow.

Built for

  • DBAs reviewing query regressions
  • Developers needing plan context
  • Teams preparing for performance reviews
  • Consulting engagements that need repeatable evidence capture

Early access

QPI is not being positioned as a finished platform.

It is being developed from the same evidence patterns used in SQL Server performance reviews: plans, Query Store data, runtime context, regression signals, and the practical need to explain what changed. The aim is to reduce the time spent jumping between disconnected evidence sources and improve the quality of the performance conversation.

For DBAs

Support faster triage of regressed queries, poor plan choices, and recurring workload pain.

For developers

Make performance evidence easier to understand before a release becomes a production problem.

For teams

Create a more repeatable way to capture, compare, discuss, and prioritise query-performance evidence.
