## What it is
A set of scripts and patches that build a Linux kernel with a WebAssembly architecture port, runnable in the browser. It combines LLVM toolchain patches, a fake-llvm wrapper, and kernel patches to boot Linux 7.0 as wasm32/wasm64 with BusyBox userland.

## Use cases
- run linux in the browser via webassembly
- boot a linux kernel compiled to wasm
- experiment with a wasm arch port of the linux kernel
- try shell commands in a browser-based linux demo
- build a linux/wasm operating system from source

## When to choose
- you want to run or hack on a Linux kernel port targeting WebAssembly
- you need a proof-of-concept browser-based Linux environment
- you're researching Wasm as a compilation target for OS-level software

## When to avoid
- you need a stable or secure system for real workloads
- you need virtio, device tree, MMU, or ELF support
- you want a production-ready browser Linux sandbox

## Facets
- artifact type: application
- maturity: experimental
- function: compiler, build-tool, simulation
- domain: operating-systems, compilers, web-development
- platform: browser, wasm
- tags: linux-kernel, webassembly, operating-system, llvm, proof-of-concept, busybox, browser-demo, linux, docker
