NET Reactor is the only tool which offers Code Encryption for Windows, Linux and OSX.

.NET Reactor offers a fully managed licensing solution for .NET applications and libraries. You can directly apply trial versions to already compiled assemblies and hardware lock license files. If required there is an SDK to programmatically load license files and check the license status.


.NET Reactor supports all dotnet implementations including .NET Framework, .NET 5.0, .NET Core and ASP.NET Core. This way there is full protection support for Xamarin, Unity and Blazor assemblies.


You can use .NET Reactor through the intuitive GUI or via command-line. Our command-line generator makes it very easy to use .NET Reactor in scripts. A Visual Studio Add-in and DevOps Tasks help you to integrate Reactor into your build environments.

We compared different obfuscators and .NET Reactor was the only one which met and indeed exceeded our expectations. We switched from Dotfuscator to .NET Reactor and have not looked back since.
