Package and Release the Binary
Build, optimize, and distribute it.
Package and Release the Binary 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.
From Code to Product
Your tool works on your machine. The last step is turning it into a fast, shareable binary others can download and run. 🚀
Build with the Build System
For a real release, drive the build through build.zig. One command compiles your project into an artifact in the zig-out folder.
zig buildOptimize for Release
Debug builds add safety checks that slow things down. Pass an optimize flag to strip them and produce a fast production binary.
zig build -Doptimize=ReleaseFastFast or Small
Choose your goal: ReleaseFast favors raw speed, while ReleaseSmall shrinks the binary size. ReleaseSafe keeps checks but still optimizes.
zig build -Doptimize=ReleaseSmallBuild a Single File Fast
For a quick one-off binary without build.zig, use build-exe directly on your source file. Great for small standalone tools.
zig build-exe src/main.zig -O ReleaseFastCross-Compile Anywhere
Zig's superpower: build for other systems with one flag. The -target triple names the OS, architecture, and ABI you want.
zig build -Dtarget=x86_64-linux-muslStatic Binaries with musl
Linking against musl produces a fully static binary with no runtime dependencies. Users just download one file and run it.
Ship for Every Platform
Run the build once per target to produce Linux, macOS, and Windows binaries from your single machine, no other compilers needed.
zig build -Dtarget=aarch64-macosFind Your Artifact
The build system drops your finished executable in the zig-out/bin directory by default. That file is what you upload and distribute.
Try Before You Ship
Wire a run step into build.zig so zig build run compiles and launches the tool, letting you smoke-test the release build instantly.
zig build run -- input.txtVersion and Release
Tag a version, attach the per-platform binaries to a release page, and write short usage notes. Now anyone can grab and run your tool. 🎉
Quick Check
Recall which flag tells Zig to build a fast, optimized binary.
Recap
You built with ReleaseFast, cross-compiled with -target, made static musl binaries, and found them in zig-out. Your CLI is ready to ship. 🎯
