sandbin

Runs untrusted code safely with no Docker, root, or VM

Webfreeglobal

sandbin runs untrusted code and survives it, giving each submission its own process namespace, empty network stack, isolated filesystem view, and restricted syscalls, without needing Docker, root access, or a virtual machine. It's built for developers building platforms that execute untrusted, user-submitted code and want lightweight kernel-level isolation.
