CCFinderSW vs CodeMatch

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.

CodeMatch is a Windows program from SAFE Corporation for comparing source-code files across two directories, including their subdirectories. It ranks file pairs by correlation scores from 0 to 100, helping an examiner reduce many combinations to a smaller review list. Its hybrid methods compare statements, comments and strings, instruction sequences, and identifiers. Reports can show the material behind high correlations in detailed HTML, while a database export can produce an HTML summary. SAFE lists languages including C, C++, C#, Java, JavaScript, Python, SQL, Swift, Verilog, and VHDL, and says requested languages can usually be added within days. The maker also describes uses such as finding open-source code in proprietary software, assessing common authorship, and identifying shared algorithms. A press release allows no-charge comparison of up to 1 megabyte of source code. CodeMatch assists expert review rather than precisely identifying plagiarism. It is paid, with a free plan and trial, but no CodeMatch price is listed.
