SaveDiff — Offline JSON Save-File Inspector

SaveDiff is an offline browser tool for developers, modders, QA testers, and technical designers who need to see exactly what changed between two JSON save files.

Features: recursive nested JSON diff; added/removed/changed paths; fast path/value search; full old/new inspection; structured JSON export; drag-and-drop files; zero install; zero telemetry; zero cloud upload; zero external dependencies.

Useful for game-save debugging, mod testing, configuration regression checks, balance tuning, QA snapshots, and before/after state inspection. Your save files never leave your machine.
