ReSharper

ReSharper is a .NET development extension that combines code analysis, editing assistance, refactoring, and navigation. It is best suited to developers working in C# and related languages who want these tools inside their editor. Its breadth is compelling, but commercial use carries a substantial annual per-user price.

Overview

ReSharper supports a wide range of languages, from C#, Visual Basic, and C++ to web and project formats such as JavaScript, TypeScript, XAML, MSBuild, JSON, and Protobuf. That reach can help teams working across a mixed .NET codebase, although the free non-commercial plan is limited to C# in VS Code and compatible editors.

The VS Code edition also works in Cursor, Antigravity IDE, Devin Desktop, Kiro IDE, and other compatible editors. It runs on Windows, macOS, and Linux for x64 and ARM64, including Apple silicon. It requires .NET SDK 6.0 or later on PATH. After the backend downloads when a solution is first opened, it can work offline except for registration and NuGet package restore.

Key features

On-the-fly analysis covers C#, VB.NET, XAML, ASP.NET, HTML, and XML, giving developers feedback while they work rather than only at a later review stage. Editing tools include extended IntelliSense, namespace imports, code rearrangement, documentation display, and code transformations. Generation actions create properties, overloads, implementations, and comparers, which can reduce repetitive typing in routine .NET work.

Refactoring spans small transformations and solution-wide changes, with batch refactoring available. Navigation jumps to files, types, and members, and follows symbols to usages, base or derived symbols, and implementations. This combination is useful in larger projects where tracing relationships and applying consistent changes can take time.

A unit test runner, debugging assistance, code templates, project dependency viewing, internationalization assistance, and AI assistance round out the toolkit. The range is a strength for developers who want several kinds of help in one extension; those seeking only a focused analyzer may find the wider package and its price unnecessary. JetBrains directs users with questions or technical difficulties to its Knowledge Base and community forum.

Pricing

The ReSharper Non-Commercial plan costs free and provides non-commercial use with C# support in VS Code and compatible editors. It is a practical option for eligible personal or other non-commercial C# work, but it does not provide the broader language coverage and editor extensions described for the paid plan.

ReSharper costs $389 a year, billed per user per year. It includes extensions for Microsoft Visual Studio, Cursor, Google Antigravity, VS Code, and compatible editors. That makes it the relevant plan for commercial developers who need the broader editor support; the per-user annual term is a meaningful commitment for individuals or teams.

A free 30-day trial starts after installation. When it ends, use requires a commercial license or a free license for non-commercial use.

Platforms

ReSharper is offered as an extension and supports Windows, macOS, and Linux. Its VS Code edition supports x64 and ARM64, including Apple silicon on macOS, and requires a .NET SDK version 6.0 or later available on PATH. The offline capability is useful for disconnected work after the initial backend download, with registration and NuGet package restore remaining exceptions.

Who it's for

ReSharper is a strong fit for .NET developers who regularly analyze, navigate, generate, and refactor code, especially in projects spanning multiple supported languages. Commercial users should expect to justify an annual license per user. Non-commercial C# developers using VS Code or a compatible editor can start with the free plan; developers who need only a narrow slice of the toolkit may prefer a more focused alternative.

Pros and cons

• Pro: Analysis, editing, navigation, and solution-wide refactoring are gathered in one extension, reducing the need to assemble separate tools for those tasks.
• Pro: The VS Code edition supports Windows, macOS, and Linux across x64 and ARM64, and can work offline after its initial backend download, apart from registration and NuGet restore.
• Pro: Non-commercial C# users have a free option, with a 30-day trial for evaluating the product before choosing a license.
• Con: The free plan is restricted to non-commercial use and C# in VS Code and compatible editors, so it is not a substitute for the broader commercial offering.
• Con: The commercial plan is $389 per user per year, which may be hard to justify for developers who need only basic or occasional code assistance.
• Con: VS Code users must have .NET SDK 6.0 or later on PATH, an added requirement to account for when setting up an editor.

Verdict

Choose ReSharper if .NET work demands frequent analysis, refactoring, and code navigation across a broad set of languages and editor environments. Its main advantage is the breadth of assistance in one extension; its main reason to look elsewhere is the 389.00 USD annual per-user license when a free or narrower tool would cover the job.
