Playground

Code playgrounds.

Write and run code in secure microVM sandboxes. No setup, no risk.

fn main() {
  println!("Hello, Rust!");
}

const greet = (name: string) =>
  `Hello, ${name}!`;
console.log(greet("world"));

const nums = [1, 2, 3];
const sum = nums.reduce((a,b) => a+b);
console.log(`Sum: ${sum}`);

<?php
$name = "World";
echo "Hello, $name!";

SELECT name, count
FROM users
WHERE active = true;

const std = @import("std");
pub fn main() !void {
  std.debug.print("Hi!", .{});
}

How it works

Each playground runs in its own virtual machine.

Write code, hit run, see the output. When you're done, the VM is destroyed. No traces left behind. No state shared between sessions.
