jscpd vs sigmap
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.; sigmap: SigMap builds a deterministic, auditable signature-and-evidence map of your codebase without LLM calls or embeddings. It allows AI agents, CI, and reviewers to trust and verify code references, significantly reducing token usage and improving task success rates.
