CCFinderSW vs CloneWorks

CCFinderSW is a free, open-source command-line tool that detects similar code pairs through token-based clone matching. It takes a source directory, a language, and an output file as command-line arguments. The default minimum clone-token threshold is 50 and can be changed with the -t argument. Output can use CCFinder, CCFinderX, CCFinderSW text, or JSON formats, and clone-pair results can be read by Gemini or CCFX. A comment rule file is required for the target language; a reserved-word list is optional but recommended. Without that list, the tool detects type 1 clones; with it, it detects type 1 and type 2 clones. It excludes pairs containing inserted or deleted sentences. The implementation is Java-only, and the project recommends Java 8 or later. Windows is the listed platform, with Windows 10 Pro named as its test environment. The repository offers a CCFinderSW-1.0.zip download and includes an MIT license for the project; bundled libraries use Apache License 2.0.

CloneWorks prepares source code into fragments and detects code clones in those fragments. It supports Linux, macOS, and Windows, with a token-based detection method and repository-level scan scope. Its input builder supports Java, C, C++, C#, and Python, and can extract blocks, functions, or files. The detector accepts a minimum similarity threshold from 0.0 to 1.0; the repository describes a Type-3 clone-detection test run. When an index exceeds available memory, a partitioned partial-index mode is available, though the README says its partition size must be determined experimentally. CloneWorks requires FreeTXL 10.6 or later, gcc, make, and Java 7 or later. The input builder runs more slowly on Cygwin because process creation is slower on Windows. It is free to use, with acknowledgement required; copies, modifications, and derivatives must remain under the license and be distributed without charge. The license also provides the software as-is without warranty.
