In their own words
CloneWorks
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.
CopyPaste
CopyPaste is a free, local-first clipboard manager for Windows and macOS. It saves clipboard history for text, images, files, folders, links, audio and video, with previews tailored to the content. Full-text search, pins, custom labels and colors, and filters by content, category and item type help organize saved items; it also supports snippets and rich text. The project says history stays on the device, without cloud storage, servers, syncing, telemetry, analytics or accounts. CopyPaste works offline and excludes passwords and clipboard content from password managers such as 1Password and Bitwarden. The standalone version checks for updates without sending user data. Windows requirements are Windows 10 version 1809 or later, or Windows 11 on x64. On macOS, it requires Ventura 13.0 or later and has a universal binary for Apple Silicon and Intel. Linux support ended after v2.11.0, and those builds receive no fixes, security updates or new features. CopyPaste is open source under GPL-3.0; redistributing it within another product requires separate terms.
