How It WorksZig
Overview
This Zig formatter cleans up code with inconsistent indentation or mixed styles into a standard format, powered by a WebAssembly build of zig fmt — the output is identical to running the zig fmt command locally. Everything runs locally in your browser; your code never leaves your device.
