Duplicate File Finder alternative: Peekaboo vs Duplicate File Finder
By Vishva Variya · Updated
Nektony’s Duplicate File Finder has a free version and a Pro upgrade priced from $7.95 a month. It compares files byte by byte, spots similar photos and songs, scans iCloud, Dropbox and Google Drive folders, and can merge folders that drifted apart. Peekaboo overlaps on the core job and differs around it: no folder merge or music matching, but a library, search and disk tools wrapped around the duplicates.

Why pick Peekaboo over Duplicate File Finder?
No monthly plan
Peekaboo is a single purchase per Mac after a 14-day trial. Nektony lists Pro pricing from $7.95 a month.
Sized first, then hashed
Files are bucketed by size before anything is read, then confirmed by SHA-256, so scans stay quick and only true copies match.
Tell the copies apart
The inspector shows each copy’s location and download source, so the attachment you saved twice is easy to tell from the one you filed on purpose.
Peekaboo vs Duplicate File Finder, job by job
| Job | Duplicate File Finder | Peekaboo |
|---|---|---|
| Exact duplicates | Byte-by-byte comparison | SHA-256, size-bucketed first |
| Similar files | Similar photos and music | Look-alike photos; no music matching |
| Merging folders | Yes | Not offered |
| Getting removed files back | Removal history, restore from the Trash | Undo timeline restores a whole session in one click |
| Price | Free; Pro from $7.95/month | One-time, 14-day free trial |
The honest verdict
Start with Nektony’s free version if you need a one-off scan, or if merging folders and matching similar songs matter to you; Peekaboo does neither. If you’d rather not rent a duplicate finder, Peekaboo does the matching for a single price and keeps searching and mapping your disk once the copies are gone.
