Nebulet is a proof-of-concept microkernel written in Rust that executes WebAssembly modules in Ring 0 within a single address space. It uses the Cranelift compiler to translate WebAssembly to native code, enabling low context-switch overhead and syscalls implemented as plain function calls.

Use cases

• run webassembly modules as an operating system usermode
• research low-overhead syscall designs in a microkernel
• experiment with sandboxed wasm execution in ring 0
• study verified wasm memory isolation without bounds checks
• build an experimental rust-based operating system kernel

When to choose

• you are researching novel OS designs that run wasm natively in kernel space
• you want a minimal microkernel codebase to study or extend in Rust
• you need a proof-of-concept for syscall-as-function-call performance ideas

When to avoid

• you need a production-ready operating system or general-purpose kernel
• you want to run existing applications or drivers
• you expect active maintenance or stable releases
