JetBrains Rider vs ReSharper: What are the differences?

JetBrains Rider is a cross-platform integrated development environment (IDE) designed for .NET and C# development. ReSharper is a plugin for Visual Studio that enhances the IDE with features for code analysis, refactoring, and productivity improvements specifically for C# development. Let's explore the key differences between them.

1. Integration with IDEs: JetBrains Rider is a standalone IDE, while ReSharper is a plugin for various JetBrains IDEs, such as Visual Studio, IntelliJ IDEA, and Rider itself. This means that ReSharper can be seamlessly integrated into existing IDE workflows, whereas Rider provides a complete development environment out-of-the-box.

2. Language Support: JetBrains Rider supports a wide range of programming languages, including C#, VB.NET, JavaScript, TypeScript, HTML, CSS, SQL, and more. On the other hand, ReSharper focuses primarily on improving the development experience for C# and VB.NET. If you are working on projects in multiple languages, JetBrains Rider provides a more comprehensive solution.

3. Code Analysis and Inspections: Rider and ReSharper both offer powerful code analysis features, but ReSharper has a stronger focus on code inspections and refactoring possibilities. ReSharper provides a vast collection of automated code refactorings, quick-fixes, and code inspections to improve code quality and maintainability. While Rider also provides these capabilities, it may not offer as extensive a collection as ReSharper.

4. Debugger Integration: JetBrains Rider has a built-in advanced debugger that supports debugging for applications written in various programming languages. ReSharper, being a plugin, relies on the debugger of the underlying IDE. JetBrains Rider's debugger integration allows for a more seamless debugging experience since it is purpose-built for the Rider IDE.

5. UI and User Experience: JetBrains Rider has a modern and intuitive user interface that is designed specifically for its standalone IDE. ReSharper, being a plugin, inherits the UI and user experience of the host IDE, which may differ across JetBrains IDEs. This means that JetBrains Rider can provide a more consistent and tailored user experience compared to ReSharper.

6. Pricing and Licensing: JetBrains Rider and ReSharper have different pricing models and licensing options. ReSharper offers a subscription-based license that covers all JetBrains IDEs, while JetBrains Rider requires a separate license. The pricing structure may vary based on different factors such as personal, business, or academic use. It is recommended to check JetBrains' website for the most up-to-date information on pricing and licensing details.

In summary, JetBrains Rider provides a standalone development environment with comprehensive language support, advanced debugger integration, and a modern user interface. ReSharper, as a plugin, offers strong code inspection and refactoring capabilities for specific JetBrains IDEs.
