Zig 0.16 · no installation required

Zig Playground Online

Free Zig playground and online compiler. Write, compile, and run Zig code in your browser with no install. Practice comptime, allocators, C interop, and systems programming with immediate feedback.

Open the Zig playground

A small Zig starter

Review this deterministic example, then open it in the full sandbox when you are ready to edit and run code.

const std = @import("std");

pub fn main(init: std.process.Init) !void {
    try std.Io.File.stdout().writeStreamingAll(init.io, "Hello, Zig!\n");
}

Expected output

Hello, Zig!

Common uses

  • Try comptime expressions
  • Practice memory-safe systems code
  • Read compiler feedback

Know the limits

Use the sandbox for small, single-file programs. Cross-compilation, external packages, build graphs, and long-running processes need a local Zig toolchain.
