True. bubblewrap and similar (Landlock, sandbox-exec on Mac) are solid lightweight options. The main difference is they still expose a syscall interface that you then restrict, vs WASM where capabilities are opt-in from zero. Different starting points, similar goals.

Some advantages of building the sandbox in wasm, aside from the security benefits, are complete execution reproducibility. amla-sandbox controls all external side effects, leaving the wasm core as just "pure computation", which makes recording traces and replaying them very easy. It's great for debugging complex workflows.
