In their own words
CodeRush
CodeRush is a Visual Studio extension for code generation, refactoring, navigation, formatting, debugging, testing, and code coverage. It includes more than 100 refactorings and intelligent code providers, with refactoring support described for C#, Visual Basic, and XAML. Its test runner supports NUnit, MSTest, xUnit, and MSpec without configuration, plus .NET Core, .NET Framework, and multi-target projects. Code style can be set for an individual developer, a solution, or a team, and cleanup can run when documents are saved. The listed IDEs are Visual Studio 2026 and Visual Studio 2022. CodeRush is available free for commercial use, with the same features and updates across free and paid subscriptions. A paid plan is listed from $249.99/user/yr, and a 30-day trial is listed. AI features require an OpenAI API key; voice input requires an Azure Cognitive Services Speech API key. Technical support is available to owners of qualifying DevExpress subscriptions; free users can search the support database.
Comby
Comby is a free, open-source tool for searching and changing code structure with lightweight templates. It recognizes basic syntax in code, strings, and comments across many languages, with parsers listed for C/C++, C#, Go, Java, JavaScript, Python, Rust, Swift, and TypeScript, plus a generic matcher for other formats. The project targets large refactors and one-off changes, and an interactive review mode lets users inspect proposed edits. Comby can run from its command line, Python bindings, or HTTP requests sent to a server on your machine. Installation instructions cover macOS with Homebrew, Ubuntu, Windows through Ubuntu on WSL, and Docker; building from source is also described. Linked projects include an Emacs package and a prototype VS Code extension. Other uses include structural code search, compiler fuzzing, test-case reduction, editor find and replace, and academic research. Comby matches balanced delimiters while accounting for comments and string literals, and supports regex search. It is self-hosted and available for API, Linux, macOS, and Windows use. The Apache-2.0 license is identified in the public repository.
