System requirements

Code editors

You can use ReSharper in Visual Studio Code, Cursor, Antigravity IDE, and other compatible code editors. Use a current stable release of your editor.

Operating systems and architectures

ReSharper runs on the following platforms:

• Windows on x64 and ARM64

• macOS on x64 and Apple silicon (ARM64)

• Linux on x64 and ARM64

The backend that matches your platform is downloaded automatically the first time you open a solution. Offline VSIX packages are published for each platform separately — refer to Install from VSIX.

.NET SDK

A .NET SDK, version 6.0 or later, needs to be installed and available on PATH. The SDK is what builds, restores, runs, and debugs your code; ReSharper delegates those operations to it. You can download it from the .NET download page.

Projects that target older frameworks are still analyzed, but building and running them requires an SDK that can build those targets. To point ReSharper at a specific SDK installation, set the custom .NET CLI path in ReSharper settings.

Network access

The first time you open a solution, ReSharper downloads its backend from download.jetbrains.com. Allow access to that host, or install an offline VSIX package instead. After the backend is downloaded, ReSharper no longer needs a network connection, except to register the product and to restore NuGet packages.

Licensing

A free 30-day trial starts automatically after installation. After the trial period, ReSharper requires a commercial license or a free license for non-commercial use.
