Gokrazy-tools is a small command-line utility that helps you turn a Raspberry Pi (or similar single-board computer) into a dedicated appliance running only the software you choose. Instead of installing a full operating system with countless background services, update managers, and configuration files, you get a minimal setup that boots straight into your application. The included tool, called gok, lets you build a complete system image from your own Go programs. You point it at the packages you want, and it produces a ready-to-flash image containing the Linux kernel, your application, and the bare minimum needed to run. You write that image to an SD card, boot the device, and it starts your program automatically. There's no package manager to maintain, no shell to log into by default, and no traditional operating system to keep patched and configured. This approach appeals to developers and hobbyists who want to deploy something to a small board and have it reliably run without ongoing maintenance. Common use cases include a small home DNS server, a Wi-Fi router, a sensor data collector, or any lightweight service that should run unattended. If you've ever wanted the simplicity of a single-purpose embedded device but with the convenience of writing your application in Go, this is aimed at that gap. The README itself is sparse and points to the project's website for documentation, including a quickstart guide covering installation and basic usage. Beyond that, the repository doesn't go into further detail about features, configuration options, or supported hardware. Anyone interested in trying it out will need to consult the external documentation to understand the full workflow and what devices are supported.
