Is it same as running bash with wasm on a constrained folder on a home ? If not what is the difference?

Bash (even if you find a way to compile it to wasm) will need POSIX to operate and also file system.

Bashkit reimplements portion of POSIX and have own FS, so there is no need a dependency on any resources outside of process (except CPU and Mem) if you do not need them. You effectively can run tons of isolated instances in parallel.
