CodeRush

CodeRush is a Visual Studio extension for developers who want refactoring, code navigation, testing and related productivity tools in one desktop workspace. It is particularly suitable for C#, Visual Basic and XAML teams that value extensive cleanup and integrated test runs. The free commercial edition makes it compelling when support and source access are not priorities.

Overview

CodeRush combines code generation, refactoring, navigation, formatting, debugging, testing and code coverage. Its breadth favors developers who prefer working inside Visual Studio instead of assembling separate utilities. DevExpress, the maker, dates its history to 1998 and is headquartered in Glendale, California.

Visual Studio Marketplace and the IDE's Manage Extensions window provide installation, and Visual Studio can update the extension automatically through Marketplace. The supported IDE table includes Visual Studio 2026 and Visual Studio 2022.

Key features

Refactoring and code style

More than 100 refactorings and intelligent code providers give CodeRush substantial scope for restructuring projects. C#, Visual Basic and XAML receive the stated refactoring support; the broader language list also includes Blazor, JavaScript, TypeScript, HTML and Razor. Project-level and batch refactoring suit both targeted changes and large cleanups.

Style rules can be set for an individual developer, a solution or an entire team. Cleanup can run when documents are saved, which helps enforce consistency without a separate formatting step. The approach is strongest for teams already standardized on Visual Studio, rather than users seeking an editor-independent workflow.

Testing, debugging and AI

The integrated runner handles NUnit, MSTest (VS Testing), xUnit and MSpec without configuration. It supports.NET Core,.NET Framework and multi-target projects, while local, automated and real-device testing are listed capabilities. This is useful for developers who want test execution beside code editing, although it remains an IDE-centered tool rather than a standalone test service.

AiGen can use GitHub Copilot through a GitHub OAuth token. CodeRush documentation requires an OpenAI API key for AI features, and voice input additionally requires an Azure Cognitive Services Speech API key. Those prerequisites matter to teams with strict credential or cloud-service policies.

Pricing

The CodeRush plan costs free. All versions are free for commercial use and receive the same features and updates as paid subscriptions. The important concessions are technical support and source code: support requires a paid subscription, and free CodeRush source code is not included. Free users can search the support database.

Paid pricing starts at $249.99/user/yr, with a 30-day trial. A paid subscription is the practical choice for organizations that need direct DevExpress technical support; the free plan is the better fit for individuals and teams comfortable with self-service help. No seat allowance or renewal condition is stated.

Platforms

CodeRush is delivered as a desktop extension and is listed for Linux, macOS and Windows, with browser coverage listed as both. Its documented IDE integration is Visual Studio 2022 and 2026, so platform suitability ultimately depends on having a supported Visual Studio setup. Minor updates are shown as available for the displayed version range, while security updates are shown as unavailable.

Who it's for

Choose CodeRush for commercial development teams using Visual Studio that want broad refactoring, team style controls and a built-in runner across common.NET test frameworks without licensing cost. It also suits individual developers who can manage their own support. Look elsewhere if direct technical assistance, source access or an editor-agnostic testing environment is essential.

Pros and cons

Pros

Free commercial use with the same features and updates as paid subscriptions.

Over 100 refactorings, intelligent providers and batch project cleanup.

Test support for NUnit, MSTest, xUnit and MSpec across.NET Core,.NET Framework and multi-target projects.

Style settings can be shared at developer, solution or team level, with cleanup on save.

Cons

Technical support requires a paid subscription, limiting assistance for free users to the support database.

Free users do not receive the source code.

AI and voice features require external API credentials.

The documented experience is centered on Visual Studio rather than an independent development environment.

Alternatives

ReSharper is the closer paid comparison for Visual Studio users who want a freemium option, a free non-commercial plan and a stated $389.00 paid plan with a trial.

Roslynator is preferable when free Roslyn-based tools and extensions are enough and no trial is needed.

ast-grep fits users seeking a free, cross-platform structural code-search and transformation tool outside a Visual Studio-only workflow.

Sourcery is the better choice for open-source projects wanting AI reviews, pull-request summaries and one-click fixes on its free plan.

OpenRewrite suits teams wanting an Apache-licensed, repository-at-a-time transformation framework running on Linux or self-hosted infrastructure.

Moderne is aimed at organizations that need a managed backpatch service and dedicated staff rather than an IDE extension.

CodART is an MIT-licensed option for API, Linux, self-hosted or web workflows; SciTools Understand requires a separate professional license.

jSparrow is an open-source alternative for users who prefer its no-license-needed model.

For browser-focused work, the Cross-Browser Testing Software directory is a better starting point; for comparing refactoring products, see Code Refactoring Tools.

Verdict

CodeRush is an excellent fit for Visual Studio developers who want unusually broad refactoring, style and test-runner coverage at no commercial license cost. Its main reason to look elsewhere is the support and source-code gap on the free plan, compounded by AI credential requirements and dependence on the Visual Studio environment.
