Balance Regression Lab

Balance Regression Lab is a Windows desktop tool for testing the impact of gameplay-data changes at scale.

Import your existing CSV, XLSX or JSON data, define the metrics and thresholds you care about, then compare your original data against updated values or experimental candidates.

The tool automatically runs large scenario sweeps and surfaces the most important regressions, threshold breaches and data errors — while keeping the full results available for inspection and export.

What it does

• Compare baseline vs updated gameplay data
• Create and test non-destructive parameter changes
• Define custom metrics and alert thresholds
• Run large multi-dimensional scenario sweeps
• Rank and summarize the most important issues
• Inspect detailed results
• Export results and transformed data to CSV, XLSX and JSON
• Save and reopen complete .brlab projects
• Fully local and offline — original source files are never overwritten

Performance

Balance Regression Lab is designed for large combinatorial workloads.

Our production benchmark processed:

10,000,000 scenarios × 5 metrics = 50,000,000 metric evaluations in ~7.5 seconds

on the reference Windows browser benchmark environment.

Actual performance depends on your hardware, formulas, dataset and number of retained issues.
