Servy is a tool that enables users to run arbitrary applications as native Windows services, with control over parameters such as working directory, startup type, process priority, and environment variables. It provides a GUI, CLI, and PowerShell module for configuring and managing services. The software supports features like logging, health checks, automatic restarts, and scripting hooks for pre-launch or post-launch actions. It is intended for users who understand the implications and risks of running software as background services.
