Bun's standalone executables are great, but as far as I'm aware unlike Deno and Node there's no cross compilation support, and Node supports more CPU/OS combinations than either Deno or Bun. Node supports less common platforms like Windows ARM for example (which will become more important once the new Snapdragon X Elite laptops start rearing their heads [1]).
We'll add cross-compilation support and Windows arm64 eventually. I don't expect much difficulty from Windows ARM once we figure out how to get JSC to compile on that platform. We support Linux ARM64 and macOS arm64.
