## What it is
TamaGo is a framework that enables compilation and execution of Go applications directly on bare metal processors, without any underlying operating system or C runtime. It consists of a modified Go distribution adding a `tamago` GOOS target plus Go packages for processor/SoC and board support, aimed at reducing firmware attack surface.

## Use cases
- write firmware in Go without an OS
- run Go on bare metal ARM or x86-64 processors
- build minimal attack surface embedded firmware
- develop secure boot or security-critical firmware in pure Go
- execute Go applications directly on SoCs like ARM or AMD64 targets
- replace C firmware toolchains with Go

## When to choose
- you want to write embedded firmware in Go with full standard library support
- you need to eliminate C code and OS dependencies from firmware for security reasons
- you target supported ARM or AMD64 SoCs/boards
- you prefer Go's memory safety for low-level embedded development

## When to avoid
- you need an RTOS or rich OS ecosystem with drivers for unsupported hardware
- your target board or SoC is not among the supported platforms
- you need hard real-time guarantees
- you require a very small binary footprint typical of C firmware

## Facets
- artifact type: framework
