This project operates by first building the webassembly module into an ELF binary and then statically linking this against the Mewz library OS in order to become a unikernel binary.

It looks still very early days in terms of supporting all libc/syscalls as well as support for different platforms.

I wonder how this compares in terms of performance to https://unikraft.org which is able to do the same but is a more establish libOS/unikernel project (disclosure I am a maintainer of Unikraft :-)) since this is written in Zig and Unikraft is written in C.
