Thanks for checking out Diffs.vip! Why we built this: - Dev teams need a truly private, fast diff workflow - JSON diffs should be structure-aware, not just text - Image diffs should highlight real changes (ΔE, overlay, heatmap) - CSV↔Parquet should be real Parquet (WASM), not a fake IPC What’s inside today: - JSON structure diff (copy “changes only”), Web Worker for large files - Image diff (changes-only / overlay / slider / heatmap), auto-align, batch export - Numbers vs Excel (cell-by-cell) - CSV↔Parquet (real Parquet, compression analysis) Roadmap (next): - Feature-point alignment for images - Batch clustering + report export - More developer APIs and guides We’d love your feedback — what should we build next?
