## What it is
container2wasm is a Go CLI tool that converts container images (e.g. Docker images) into WASM binaries that can run on WASI runtimes or in the browser. It uses emulators like Bochs, TinyEMU, and QEMU to run x86_64, riscv64, or AArch64 containers inside WebAssembly.

## Use cases
- convert docker container image to wasm
- run linux containers in the browser
- run containerized tools with wasmtime
- compile ubuntu image to wasi binary
- run containers on any wasi runtime
- sandbox container execution in webassembly

## When to choose
- you want to run existing container images as portable WASM binaries
- you need to demo Linux containers in a browser without a server
- you want to run containerized CLI tools on WASI runtimes like wasmtime or wasmer

## When to avoid
- you need native performance, since emulation adds significant overhead
- you need GPU, complex networking, or full container runtime features
- you need a production-grade container runtime rather than an experimental converter
