paludariumx86-64 Linux programs, anywhere

A user-mode x86-64 Linux emulator in Rust. Run static Linux binaries on Linux, macOS, Windows and in WebAssembly.

Unchanged Linux binaries

Runs statically linked x86-64 Linux programs, such as static-musl builds of C and Rust programs, without changing them.

The same ELF runs on three native hosts, in Node.js, and in Chromium, Firefox and Safari through WebAssembly.

System calls go through an explicit table, unknown ones return ENOSYS, and a shown host directory cannot be left.

Differential tests compare every result with a real x86-64 Linux on every platform before each release.

Translates hot x86-64 code into WebAssembly; about 21 % faster than the interpreter in the measured Node.js run.
