WasmV is an experimental library OS for WebAssembly runtimes.

WasmV exposes WASI, POSIX-like APIs, and provides a virtual network interface (TUN) to WebAssembly programs. Also, it is influenced by gVisor, a container runtime sandbox developed by Google.

We currently only support Wasmtime as a runtime and WASI Preview 1.
