CodeRush vs jscodeshift

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.

jscodeshift is a free toolkit for developers who build and run codemods across JavaScript, TypeScript, or Flow projects. A codemod parses source into an abstract syntax tree, changes that tree, and generates source code. The runner applies a transform to each file and reports files that were not transformed. Its command line accepts a local transform, a URL, or paths from standard input. Parser choices include Babel, Babylon, Flow, TypeScript, and TSX, with Babel as the default. Users can set child-process limits, choose extensions, exclude paths with ignore patterns or configuration files, and preview changes in dry-run mode. The API supports traversal, filtering, finding, replacing, inserting, removing, and renaming syntax-tree nodes, with optional formatting during output. jscodeshift wraps recast to help preserve source style. Jest and Jasmine utilities support fixture or inline tests, and VS Code debugging guidance is documented. It runs on Linux, macOS, Windows, or self-hosted environments under an MIT license.
