What You Can Build with Zig
CLIs, embedded, game engines, and OS-level code.
What You Can Build with Zig is a free Zig Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Zig Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
A Language for Real Software
Zig is not a toy. Its speed and control make it a fit for serious software, from tiny chips to whole operating systems. 🚀
Command-Line Tools
Zig is great for CLI tools: it starts instantly, produces a single small binary, and reads command-line arguments through the standard library.
Embedded and Firmware
With no runtime and optional heap-free code, Zig suits embedded devices. You can target microcontrollers and run on bare metal.
Game Engines and Graphics
Predictable performance and manual memory make Zig appealing for game engines, where steady frame times matter more than convenience.
Operating System Code
Zig can produce freestanding binaries with no operating system underneath, so it is usable for kernels, bootloaders, and low-level OS work.
High-Performance Libraries
Because it compiles to lean native code, Zig is handy for fast libraries that other languages can call through a simple C interface.
A Better C Compiler
Surprisingly, Zig is also a drop-in C compiler. The zig cc command builds C and C++ projects and cross-compiles them with ease.
zig cc -o app main.cWebAssembly Targets
Zig can compile to WebAssembly, letting you ship fast, compact modules that run in browsers or other Wasm hosts.
Networked Services
Low overhead and direct control over memory make Zig a solid choice for servers and networking code that must handle heavy load efficiently.
Start Small, Grow Big
You will begin with a short main function that prints a line, then steadily grow into the bigger projects above as you learn.
pub fn main() void {
std.debug.print("Building with Zig\n", .{});
}Your Path from Here
Next you will install Zig and run your first program. From that one step, every project in this list becomes reachable.
