Our verdict on CCDetect-lsp
CCDetect-lsp is an open-source Language Server Protocol tool that detects duplicate code, or code clones, and reports diagnostics in an editor. It is aimed at developers who want clone feedback while editing rather than a separate review workflow, particularly solo developers and small teams. The project describes itself as language agnostic and uses Tree-sitter grammars, with language-specific queries to select fragments such as functions, methods, classes or whole files.
Its main strength is configurable incremental detection. Developers can set a minimum clone-token threshold, ignore AST nodes, or treat selected nodes as interchangeable to detect Type-2 clones. Detection can update on save or during editing, and clone diagnostics are exposed through editor integrations. Setup documentation covers Visual Studio Code and Neovim, and the repository includes a Docker-based demo. The server itself is built locally from source, so this suits developers comfortable with a source-based setup more than teams seeking a hosted, ready-to-use service.
CCDetect-lsp focuses on editor diagnostics rather than a broader duplication-management workflow. The repository does not document CI or pull-request reporting, duplication gates, or trend visualisation, so teams that need code-review automation or repository-wide tracking should consider a tool built around those workflows. There is no hosted tier to compare: the project is open source, with community support. Choose it for configurable clone detection close to the editing process; look elsewhere if deployment convenience or CI controls matter more than immediate editor feedback.
