Pros
  • AST-based semantic, exact, and structural clone detection
  • Generated-code filtering, baselines, and CI checks
  • GitHub integrations plus a programmatic Go SDK
  • Detects exact and near-miss clones across repositories
  • Supports configurable normalization, abstraction, filtering, and thresholds
  • Produces clone-pair and clone-class reports in XML and HTML
Cons
