NSSM vs Service+

NSSM is a Windows service helper that runs an application as a service, watches its process, and responds when it exits. A graphical interface installs or removes services, while command-line options support scripted configuration. On exit, NSSM can restart the application, ignore the event, terminate itself, or exit uncleanly so Windows recovery actions can run. It records its own progress in the Windows system Event Log and can redirect the monitored program’s input and output. Output files can rotate at a configurable size, including while the program continues running. Administrators can set process priority and CPU affinity, and start, stop, or query services. NSSM provides 32-bit and 64-bit binaries and says it should work on Windows 2000 or later. It is public domain, with source usable for any purpose. The site lists version 2.24 from 2014-08-31 as latest, plus a 2017 prerelease. Administrator access is required; documented bugs affect newer startup, XP, and large log rotation.

Service+ is a graphical console for administering Windows services. It can start, stop, or pause multiple services together, edit properties such as startup settings, account, dependencies, name, and path, and terminate a nonresponsive service process without rebooting. Administrators can permit authenticated users to start services while preventing users, including administrators, from stopping critical ones. Service configurations can be imported and exported as XML for duplication, backup, or mirroring across computers. The tool also manages services on remote computers and can attach a debugger to a service process in one click. It is freeware, listed at free, and the plan specifies Windows only and x86/x64 support through version 4.5.60. The listed system requirements span Windows NT 4 through Windows 11 and Windows Server 2025. Service+ is a native Unicode application available in English and French. The download page states that the application is provided without transmission of personal data. Active+ provides documentation, an FAQ, and a support form.
