jscpd vs sourcey

jscpd: jscpd is a powerful copy/paste detector for programming source code, capable of identifying duplicated blocks across more than 225 programming languages and digital formats. It features an AI-ready output, agent skills, and a Rust-powered engine for significantly faster detection performance.; sourcey: Sourcey is a static documentation generator that consolidates various source formats like OpenAPI, Doxygen, and Markdown into a single, self-owned HTML site. It renders all content at build time, ensuring no runtime dependencies or API calls for your documentation.
