    Windows Service Wrapper permissive

    Windows Service Wrapper permissive

    A wrapper executable that can run any executable as a Windows service

    ...You basically write a configuration file specifying how you'd like your process to be launched, and we provide programmatic means to install/uninstall/start/stop services. Another notable difference is that winsw can host any executable, whereas Java Service Wrapper can only host Java apps. Whether you like this or not depends on your taste, so I wouldn't claim mine is better. It's just different. WinSW 3 can run on Windows platforms with .NET Framework 4.6.1 or later versions installed. For systems without .NET Framework, the project provides native 64-bit and 32-bit executables based on .NET Core.
