Zig is an imperative, general-purpose, statically typed, compiled system programming language designed by Andrew Kelley.[3][4] The language is designed for "robustness, optimality and maintainability",[5][6] supporting compile-time generics and reflection, cross-compilation and manual memory management.[7] A major goal of the language is to improve upon the C language,[8][9] while also taking inspiration from Rust,[10][11] among others. Zig has many features for low-level programming, notably: packed structs (structs without padding between fields), arbitrary width integers[12] and multiple pointer types.[13]

The stage 1 compiler is written in Zig and C++, using LLVM 13[14] as a back-end,[15][16] supporting many of its native targets.[17] The compiler is open source under the MIT License.[18] The Zig compiler exposes the ability to compile C and C++ similarly to Clang with the commands "zig cc" and "zig c++",[19] providing many headers including libc and libcxx for many different platforms, allowing Zig's cc and c++ sub-commands to act as cross compilers out of the box.[20][21]

Zig development is funded by the Zig Software Foundation (ZSF), a non-profit corporation with Andrew Kelley as president, which takes in donations and hires multiple full-time employees.[22][23][24]


Hello World

const std = @import("std");

pub fn main() !void {
    const stdout = std.io.getStdOut().writer();
    try stdout.print("Hello, {}!\n", .{"world"});

Generic linked list

pub fn main() void {
    var node = LinkedList(i32).Node {
        .prev = null,
        .next = null,
        .data = 1234,

    var list = LinkedList(i32) {
        .first = &node,
        .last = &node,
        .len = 1,

fn LinkedList(comptime T: type) type {
    return struct {
        pub const Node = struct {
            prev: ?*Node,
            next: ?*Node,
            data: T,

        first: ?*Node,
        last:  ?*Node,
        len:   usize,
