ReSharper

ReSharper is a code-assistance and quality toolkit for.NET development, best suited to developers who want analysis, refactoring and navigation together across a project. Its breadth is compelling, but commercial users should weigh it against the annual per-user cost, and VS Code users need a.NET SDK on PATH.

Overview

ReSharper brings editing, code quality analysis, navigation and supporting development tools into extensions for Microsoft Visual Studio and compatible editors. The VS Code edition also works with Cursor, Antigravity IDE, Devin Desktop, Kiro IDE and other compatible editors. Its broad language support—including C#, Visual Basic, C++, JavaScript, TypeScript, HTML, ASP.NET, CSS, XML, XAML, MSBuild, NAnt, JSON and Protobuf—makes it relevant to mixed.NET codebases, though the free plan is limited to C# in VS Code and compatible editors.

After downloading its backend when a solution is first opened, the VS Code edition can work offline except for product registration and NuGet package restore. That is useful for developers who cannot rely on a constant connection, but it does not remove those two network-dependent tasks.

Key features

On-the-fly analysis covers C#, VB.NET, XAML, ASP.NET, HTML and XML, giving developers feedback across both application code and common project markup. Editing assistance combines extended IntelliSense with namespace imports, code rearrangement, transformations and documentation display. Generation actions create properties, overloads, implementations and comparers, reducing repetitive coding within supported workflows.

Refactoring ranges from small transformations to solution-wide changes, with batch refactoring available. Navigation jumps to files, types and members, and follows symbols to usages, base or derived symbols, or implementations. Together, these tools suit developers working across large or interconnected solutions; a reader seeking only a focused refactoring utility may not need the broader package.

Additional tools include a unit test runner, code templates, debugging assistance, project dependency viewing, internationalization assistance and AI assistance. This breadth keeps several development tasks alongside code analysis, although it also means the annual license buys more than a single-purpose editor aid.

Pricing

ReSharper is freemium, with a free plan and a free 30-day trial. The trial starts after installation; when it ends, continued use requires either a commercial license or a free license for non-commercial use.

Commercial buyers should account for the per-user annual term when budgeting for a team; the 30-day trial offers a window to assess fit before that commitment.

Platforms

The product spans Windows, macOS and Linux, with extension availability. The VS Code edition supports Windows, macOS and Linux on x64 and ARM64, including Apple silicon on macOS. It requires.NET SDK version 6.0 or later available on PATH, an important setup requirement for developers evaluating that edition.

Who it's for

ReSharper is a strong fit for.NET developers who benefit from code analysis, solution-level refactoring and symbol navigation, especially across multiple supported languages. Commercial teams get the widest stated editor coverage through the paid per-user plan. Non-commercial C# developers using VS Code or compatible editors can start with the free plan. Developers who need only a narrower tool, or who cannot justify a recurring annual license for each user, should compare alternatives.

Pros and cons

Pros: Analysis, editing, generation, navigation and solution-wide refactoring are combined, making it useful across several stages of.NET work.

Pros: The VS Code edition works across Windows, macOS and Linux on both x64 and ARM64, including Apple silicon.

Pros: A free non-commercial plan provides C# support in VS Code and compatible editors, while a 30-day trial lets users evaluate before licensing.

Cons: The commercial plan costs $389 a year per user, which may be difficult to justify for developers who need only one part of the toolkit.

Cons: The free plan is limited to non-commercial use and C# in VS Code and compatible editors.

Cons: VS Code users need.NET SDK 6.0 or later on PATH, and offline use still excludes registration and NuGet package restore.

Alternatives

For a free, repository-focused option, OpenRewrite provides its core framework and Apache-licensed recipes and runs one repository at a time. Choose it when that repository-at-a-time approach fits better than ReSharper’s editor-centered toolkit. Roslynator is another free option, with tools and extensions and donations welcome; consider it when a free alternative is the priority.

ast-grep has a free plan and supports API, extension, Linux, macOS, web and Windows platforms; consider it when that platform range suits your needs. Sourcery offers a forever-free Open Source plan for public repositories, including AI reviews, PR summaries and diagrams, one-click fixes and custom review rules, making it a fit when those capabilities and public-repository terms align.

CodeRush offers all versions free for commercial use, with the same features and updates across free and paid subscriptions; choose it if those terms better fit your licensing needs. Moderne offers a fully managed service with a backpatch service and 2+ dedicated FTEs, a different direction for readers seeking managed support. CodART is MIT-licensed, though SciTools Understand requires a separate professional license. jSparrow is another alternative to consider.

Verdict

Choose ReSharper if you are a.NET developer who will use its combined analysis, editing, navigation and refactoring capabilities across a solution; the breadth is its clearest reason to pay. Look elsewhere if you need only a focused tool or the annual per-user commercial license outweighs that range. For non-commercial C# work in VS Code and compatible editors, the free plan is the practical starting point.
