Pros	AST-based semantic, exact, and structural clone detection Generated-code filtering, baselines, and CI checks GitHub integrations plus a programmatic Go SDK	Finds semantic duplicates beyond token-level similarity Supports local CPU or CUDA inference with ONNX Automates repository scans through GitHub Actions
Cons	Source analysis is focused on Go and Templ projects Self-hosted operation puts environment management on the team CLI and SDK workflows may be more than small projects need	Self-hosted installation adds deployment responsibility Amazon Bedrock embeddings may incur separate AWS charges Language support is limited to the listed programming languages
Our verdict	art-dupl is an open-source command-line tool for detecting duplicated code in Go and Templ projects. It analyzes repositories through AST-based structural detection and supports semantic, exact, structural, suffix-tree, and hash-based… Read the review →	semdup is an open-source command-line tool for identifying near-duplicate source code by comparing semantic meaning rather than token sequences. It indexes functions or code blocks, stores embeddings locally, and reports duplicate clusters… Read the review →
