## Project history and usage

container2wasm is an experimental converter that turns container images into WebAssembly artifacts runnable on WASI runtimes or in browsers. It occupies a niche where container packaging meets WebAssembly portability experiments.

### Project history

Official releases began with v0.1.0 in February 2023. The README describes support for emulation through Bochs, TinyEMU, and QEMU, along with WASI runtimes such as wasmtime, wamr, wasmer, wasmedge, and wazero.

### Adoption history

Official sources present demos and examples rather than an adopter list. The project is best understood as experimental tooling for developers exploring how existing container images can be repackaged for WebAssembly and browser-hosted environments.

### How it is used

The main `c2w` command converts a container image such as `ubuntu:22.04` into an output `.wasm` file. The companion `c2w-net` command supports networking experiments for converted WASM images, including browser and WebSocket delegation modes.

### Why package nerds care

The package is interesting because it treats a container image as an input artifact rather than as something only a container runtime can execute. For package-manager users, it exposes a command-line bridge between OCI-style image distribution, WASI runtimes, and browser demos.

### Timeline
