| Spec score · Duplicate File Finders | 8.9 (#1) | 7.3 (#20) |
| Command line | A CLI frontend supports automation and scripting. | Command-line parameters can start scans, generate CSV reports, and integrate DUDE with a user's file manager. |
| Downloads | The Czkawka GTK 12.0 release is the last, and the project says no new binaries will be provided for that frontend. | Portable executable packages are available for Linux and Windows, with separate PyInstaller and Nuitka builds. |
| Duplicate detection | Duplicate mode can compare files by name, size, partial hash or full hash. | It compares files using content hashes, so different filenames or extensions do not prevent duplicates from matching. |
| License | Czkawka core, CLI and GTK GUI are MIT licensed; Krokiet and Cedinia binaries are distributed under GPL-3.0-only because of their Slint dependency, while project artwork uses CC BY 4.0. | The project is licensed under the MIT license. |
| Purpose | Czkawka finds duplicates, empty folders, similar images, and other unnecessary files. | DUDE is a cross-platform GUI utility for finding duplicate files so users can delete or link them to save space. |

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.
