dupFinder Command-Line Tool

Last modified: 30 September 2021

dupFinder is a free cross-platform command line tool that finds duplicates in C# and Visual Basic .NET code — no more, no less. But being a JetBrains tool, dupFinder does it in a smart way. By default, it considers code fragments as duplicates not only if they are identical, but also if they are structurally similar, even if they contain different variables, fields, methods, types or literals. Of course, you can configure the allowed similarity as well as the minimum relative size of duplicated fragments.
