CCDetect-lsp vs Simian Similarity Analyzer

CCDetect-lsp has no write-up on Specifiction yet; its figures are above.

Simian Similarity Analyzer scans files in a repository and reports repeated blocks of text, including duplicated code. It analyzes human-readable material such as source files, markup, stylesheets, Markdown, and plain text. Listed languages range from Java, C, C++, C#, COBOL, and Python to JavaScript, TypeScript, HTML, XML, and CSS. The tool runs on the Java Virtual Machine, and its generated JAR works with JDK 8 or newer. It can run locally, from scripts, or in a build pipeline; the repository also documents Gradle integration. Results are plain text by default, with XML, YAML, and editor-friendly formats available. Settings include a duplicate-line threshold, file include and exclude patterns, language selection, and ways to ignore differences such as identifiers, strings, and numbers. The maker reports a JDK test processing over 2.4 million lines and finding more than 140,000 duplicate lines in under five seconds, with results varying by hardware, operating system, and options.
