## What it is
SqlQueryStress is a Windows GUI tool (with a cross-platform CLI companion, sqlstresscmd) for stress-testing SQL Server queries by running them under configurable concurrency and load. It helps measure query performance and compare execution behavior across tuning changes.

## Use cases
- stress test a SQL Server query under concurrent load
- compare stored procedure performance before and after index changes
- measure query throughput and CPU cost across many executions
- load test T-SQL queries with parameter substitution
- run repeatable query benchmarks from the command line

## When to choose
- you need to benchmark SQL Server queries or stored procedures under realistic concurrency
- you want a simple GUI tool for query load testing on Windows
- you want a cross-platform CLI for automated query stress tests

## When to avoid
- you need to load test non-SQL Server databases
- you need full application-level or HTTP load testing rather than raw query testing
- you need a distributed load generation cluster

## Facets
- artifact type: application
- maturity: active
- function: benchmarking, testing, database, cli, gui
- domain: databases, performance, developer-tools
- platform: windows, cross-platform, cli, dotnet
