ReSharper vs Roslynator

ReSharper provides coding assistance and code quality tools for.NET development. It analyzes C#, VB.NET, XAML, ASP.NET, HTML, and XML as code is written. Editing features include extended IntelliSense, transformations, namespace imports, code rearrangement, and documentation display. Developers can generate properties, overloads, implementations, and comparers, then apply refactorings across a solution or to smaller sections. Navigation helps move among files, types, and members, and follow symbols to usages, base or derived symbols, and implementations. Other tools include a unit test runner, code templates, debugging assistance, project dependency viewing, and internationalization assistance. The VS Code edition also works with Cursor, Antigravity IDE, Devin Desktop, Kiro IDE, and compatible editors. It runs on Windows, macOS, and Linux on x64 and ARM64, including Apple silicon on macOS, and requires a.NET SDK version 6.0 or later on PATH. A 30-day trial starts after installation. Afterward, use requires a commercial license or a free non-commercial license. The commercial plan costs $389 a year per user.

Roslynator is a set of code analysis tools for C# development environments built on Roslyn. Its IDE extensions offer refactorings and fixes for compiler diagnostics, while analyzers are distributed separately through NuGet packages. Listed editor extensions cover Visual Studio 2026 and 2022, VS Code, and Open VSX. The VS Code extension requires legacy OmniSharp with `dotnet.server.useOmnisharp` set to true and does not work with C# Dev Kit. A command-line tool can be installed with `dotnet tool install -g roslynator.dotnet.cli`; the CLI is also integrated into MegaLinter for CI. EditorConfig settings can configure analyzers, refactorings, and compiler diagnostic fixes, and a testing framework supports unit tests for those tools. The .NET client libraries extend the Roslyn API but do not include analyzers or refactorings. The repository is licensed under Apache License 2.0. Its security policy supports version 5.x, CLI 0.x, and the Visual Studio 2026 and VS Code extensions; versions below 5.0 and Visual Studio 2022 extensions are out of support.
