| Spec score · Duplicate File Finders | 8.9 (#1) | 7.5 (#17) |
| Downloads | The Czkawka GTK 12.0 release is the last, and the project says no new binaries will be provided for that frontend. | The repository lists a drag to Applications DMG installer and an app bundle ZIP for manual installs or in app updates. |
| Duplicate detection | Duplicate mode can compare files by name, size, partial hash or full hash. | Duplicate Finder verifies exact duplicates byte for byte and moves selected copies to Trash without permanently deleting files. |
| Integrations | The reusable czkawka_core library is used by the project’s frontends, and Python bindings are available. | The documented remote workflow uses Codex for iPhone and SSH; Meshnet can provide a private network address, but Doppel does not install a VPN or configure internet routing. |
| Privacy | The application makes no network connections and contains no telemetry, update checks or analytics. | The app has no login, analytics, telemetry, tracking, or external SDKs and accesses only folders and files selected by the user. |
| Purpose | Czkawka finds duplicates, empty folders, similar images, and other unnecessary files. | Doppel creates separate ChatGPT desktop app instances with distinct accounts, data directories, names, and icons. |
| What it does | Czkawka finds duplicate files, empty folders, similar media and other unnecessary or damaged files. | File Foundry is a native Apple Silicon macOS app with local first tools for finding exact duplicates, organizing media, and converting files with FFmpeg. |

In their own words
Czkawka
Czkawka is a free tool for locating duplicate and unnecessary files, empty folders, similar images, and related items. Its tools can find duplicate and empty files, temporary and large files, similar videos, and duplicate music. Scans can target user-selected directories and files, with matches determined by file name, size, full-file hash, or a combination of size and name. Features include file preview, automatic selection, folder exclusions, and moving items to the Recycle Bin or Trash. The project provides graphical and command-line frontends, an Android frontend, a reusable core library, and Python bindings. It says the software uses multithreading and caching to help scans and later rescans, and that it has no internet access and collects no user information or statistics. Czkawka is listed for Android, Linux, macOS, and Windows. GTK 12.0 is the final release for that frontend, and no more GTK binaries are planned. Krokiet prebuilt binaries have no mandatory runtime dependencies, although its similar-videos tool requires ffmpeg at runtime.
