What is Zig?

Zig is a general-purpose systems language emphasising simplicity, performance, and "no hidden control flow" — no implicit allocations, no hidden type conversions, no preprocessor. The standard library ships with a C/C++ compiler bundled in, so Zig can compile and link against existing C and C++ code without external toolchains.

Why run Zig in the browser

Zig's compile times are short for tiny files but the toolchain (zig + libc + linker) is still 100MB+ and OS-specific. A browser sandbox is the right tool for trying syntax, validating a buffer trick, or teaching the language without installing anything. The sandbox runs Zig 0.9.

Common Zig tasks

Systems programming (Zig is being adopted as a C replacement in some projects), embedded firmware, operating-system development (Zig is used in Bun's JavaScriptCore bindings), the standalone zig build system, and C/C++ interop without an FFI layer. The sandbox compiles to a Linux ELF and exits with the program's return code.

Getting started with Zig 0.9

Paste a snippet — const std = @import("std"); pub fn main() void { std.debug.print("hi ", .{}); } — hit Run, see stdout. The highlighter understands Zig's comptime blocks, error unions !T, optionals ?T, and the anytype generics. The default snippet shows a syscall-based exit.

Frequently Asked Questions

Is the Zig online compiler free?
Yes — Tutorsbot's Zig compiler is completely free. No account required, no installation, and no usage limits.
Do I need to install Zig?
No. The Zig compiler runs entirely in your browser. No runtime, no SDK, no PATH configuration. Open the page and start coding.
Is my Zig code saved between sessions?
Yes — your code autosaves to your browser's local storage so you can resume where you left off. You can also generate a shareable URL.
Can I share Zig code with others?
Yes. Click the Share button to copy a URL that encodes your script. Anyone with the link can open and run it instantly — no account required on their end.
Is the Zig compiler safe to use?
Absolutely. Every program runs in an isolated sandbox. Your local system is never exposed to the executed code, and nothing is persisted after the execution window.
