BrontoSource vs CodeRush

BrontoSource is a desktop tool for deterministic C++ refactoring across large repositories. Teams define explicit transformation rules and apply them across thousands of files. Documented operations include expression matching, extraction, and inlining for functions, constructors, type aliases, enumerators, namespaces, macros, declarations, types, and lambda captures. The command-line tool accepts Clang arguments, a compilation database, or compile_flags.txt, then can generate Fossil-format edits, merge edit files, and apply changes. BrontoSource describes its output as repeatable, traceable diffs for review. Its homepage reports 100M+ lines transformed safely and 10,000+ files refactored in one transformation. The product is in early access, with access arranged through BrontoSource; its API can also be tried on Compiler Explorer without installation. Pricing is on request. A header-only support library supports CMake 3.10.0+ and Bazel 8.1.1+ and uses 0BSD.

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.
