CodeMatch

What it is
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.
