Differ

Desktop app for comparing images side-by-side with pixel-level diffing

---

Pick two folders, auto-match images by filename, and compare them with three modes:

• Side-by-side — Synchronized scroll and zoom, horizontal or vertical layout
• Pixel diff — pixelmatch-powered overlay with diff percentage
• Slider — Draggable overlay to reveal differences

Save folder pairs as named projects. Session auto-restores on relaunch.
