In their own words
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.
jscpd
jscpd is a free, open-source tool for finding repeated code in repositories. It can fail a build when duplication exceeds a configured threshold, making it usable in local development and CI. The project says it supports 224 languages. Exact clones are detected by default, while renamed, near-miss, and semantic clone checks are optional; semantic detection is experimental.
Version 5 is available as a self-contained native binary that does not need Node.js, with direct macOS, Linux, and Windows binaries for x64 and ARM64. Reports include HTML, JSON, XML, README badges, SARIF, CodeClimate, and OpenMetrics. The GitHub Action can enforce a threshold and upload SARIF for GitHub Code Scanning, and GitLab CI reporters are documented. Developers can also use pre-commit hooks or Docker. A dashboard summarizes project size, duplication, complexity, dead code, and a health score. Dead-code analysis covers JavaScript, TypeScript, and Python, plus Rust when compiler diagnostics are supplied.
