Diskaroo vs dupeGuru — honest comparison
Looking for a dupeGuru alternative? Here's an honest Diskaroo vs dupeGuru comparison — and the honest part matters here, because dupeGuru is free. dupeGuru is the open-source, cross-platform duplicate finder that gets recommended by default, with fuzzy and content-based match modes. Diskaroo is paid for its exact-duplicate detection on one cross-platform license, with a disk-usage treemap built around it. If price is your only axis, you should probably use dupeGuru — we'll say that outright. This page is about the narrower group of buyers for whom Diskaroo is still worth paying for.

|---|---|---|
| Entry price | $19.99 one-time | Free |

Pick dupeGuru if
- ·Completely free and open-source (GPLv3) — this is the single biggest reason to choose it and it's a good one.
- ·Fuzzy / contents / folder match modes, including near-duplicate photos — Diskaroo is exact byte-identical only and does none of this.
- ·Runs on Linux as well as Mac and Windows.
- ·No payment, no account, no subscription — if price or match-mode depth is what you care about, dupeGuru is the right call.
- ·Mature and well known among people who dedupe regularly — a long-standing open-source staple, even though its release cadence is slow.
Pick Diskaroo if
- +Modern, signed and notarized desktop app rather than a functional-but-dated community Qt build.
- +Exact duplicate detection lives inside a disk-usage treemap with drill-in and filters — dupeGuru is dedupe-only with no space visualization.
- +Review-before-trash collector tray stages a whole batch for one deliberate confirmation — a different safety model from dupeGuru's reference-folder system.
- +One maintained product with commercial support across Mac, Windows, and Linux on a single $19.99 lifetime license.
- +Consistent UX across all three desktops with in-app auto-update.
