Could you build this?
Yes Splitting code into chunks (e.g., using tree-sitter functions), generating embeddings via an API or local model, and computing cosine similarity or vector search is easily vibe-coded.
Discussion
20 comments analyzed.
Competitors mentioned: jscpd (copy/paste detector), SemHash (deduplication library)
Concerns raised: LLM hallucination with embedding-based detection, O(n²) brute-force similarity search doesn't scale for large projects, High memory usage for large repos (4.8GB+ for Kubernetes), Performance bottleneck: ~130s+ on large projects like Kubernetes, False positives in similarity detection need manual cleanup
Feature requests: Generate and run test units to verify if similar code produces same results, More granular code chunking below function level, Local model support for embeddings, Support for additional languages (Elixir, PHP mentioned as recent additions)
