.NET Reactor

What .NET Reactor is

.NET Reactor is a code protection and licensing system for .NET assemblies, designed to make reverse engineering harder. Its protections include obfuscation, encrypted code, code virtualization, anti-debugging, string encryption, control-flow obfuscation, and anti-tamper controls. It supports assemblies targeting .NET Framework, .NET 5–10, .NET Core, .NET Standard, .NET MAUI, Xamarin, Mono, and Unity, among other listed targets. Licensing options include trial or permanent licenses, hardware and software locks, and an SDK for license checks and custom extensions. Developers can work through a graphical interface or command line; listed build integrations include Visual Studio and JetBrains Rider add-ins, Azure DevOps pipeline tasks, and GitHub Actions. Demo downloads are available for Windows, macOS, and Linux, although the Linux package includes only command-line tools. The Single Developer plan is $249, paid once and excludes build server support. The Company plan is $549, paid once, includes build server support, and applies to exactly one legal entity. The vendor lists a 14-day trial.
