A Linux-like kernel in a browser tab - deep dive in the BrowserPod architecture

I was not aware of Wanix. At a first glance, it seems similar. I can't quite understand from the project description if the linux compatibility is through emulation or syscall implementation. BrowserPod does the latter. The main goal is to run unmodified source code compiled to Wasm by providing a Linux implementation. Wanix seems more like its own new operating system interface, with a compatibility layer on top to run existing stuff.
