Comparison
DupeZappa vs dupeGuru
| Feature | DupeZappa | dupeGuru |
|---|---|---|
| Exact duplicates | Identical files grouped regardless of filename | Content-based matching in Standard mode |
| Similar images | Near-duplicates flagged for side-by-side review | Picture mode fuzzy matching |
| Beyond dedup | Rename, search, junk cleanup, tags, faces in one app | Duplicate-focused; mature and cross-platform |
| Safety | Preview before apply; undo history; Recycle Bin default | Results table review; no shared toolkit undo |
| Privacy | Files processed locally on your machine | Local, open source (GPL-3) |
| Price | One-time purchase (early access) | Free |
Preview-first and undo
Both tools expect human review for fuzzy matches. DupeZappa emphasizes preview-first apply across duplicates, renames, moves, and AI suggestions, with operation history and Recycle Bin-oriented deletes. dupeGuru's UI is functional but dated; safety is mostly on the user to read the results table carefully.
