Node.js (npm install @boxlite-ai/boxlite, Node 18+)

import { SimpleBox } from '@boxlite-ai/boxlite';

const box = new SimpleBox({ image: 'python:slim' });
try {
  const result = await box.exec('python', '-c', "print('Hello from BoxLite!')");
  console.log(result.stdout);
} finally {

}

Go (go get github.com/boxlite-ai/boxlite/sdks/go, Go 1.24+ with CGO)

ctx := context.Background()
rt, _ := boxlite.NewRuntime()
defer rt.Close()
box, _ := rt.Create(ctx, "alpine:latest")
defer box.Close()
result, _ := box.Exec(ctx, "echo", "Hello from BoxLite!")
fmt.Print(result.Stdout)

Rust (cargo add boxlite tokio futures --features tokio/macros,tokio/rt-multi-thread)

let runtime = BoxliteRuntime::default_runtime();
let litebox = runtime.create(BoxOptions {
    rootfs: RootfsSpec::Image("alpine:latest".into()),
    ..Default::default()
}, None).await?;
let mut execution = litebox.exec(BoxCommand::new("echo").arg("Hello from BoxLite!")).await?;
let mut stdout = execution.stdout().unwrap();
while let Some(line) = stdout.next().await { println!("{}", line); }

Full runnable versions: Python, Node, Go, Rust, C.

              Hardware Virtualization + OS Sandboxing
             (KVM/Hypervisor.framework + seccomp/sandbox-exec)

Security Layers:

• Hardware isolation (KVM/Hypervisor.framework)
• OS-level sandboxing (seccomp on Linux, sandbox-exec on macOS)
• Resource limits (cgroups, rlimits)
• Environment sanitization
