JSON Diff Calculator

Compare two Starborne Frontiers JSON export files to see what has changed between them. Upload your exported player data files to analyze differences in units, equipment, and engineering.

Upload Files

How It Works

Small Files (<5MB): Full recursive comparison of all properties and nested objects.

Large Files (≥5MB): Optimized comparison focusing on key Starborne Frontiers sections:

  • Units: Level, Rank, Refit changes
  • Equipment: Level, Rank, and equipment reassignment changes
  • Engineering: Level, Type, Attribute, and ModifierType changes

Equipment changes are grouped with their equipped units for better readability. Detailed Attributes fields are excluded to reduce verbosity in large files.
