Build

Requires GCC for Windows (MinGW). kcc.exe is bundled — no separate Krypton install needed.

kcc.exe run.k > out.c
gcc out.c -o kryofetch.exe -lm -w -lsetupapi -ladvapi32 -lpdh

Or just run build.bat.

Requirements

• Windows 10 / 11
• GCC (MinGW / winlibs)

Language

Written in Krypton — a self-hosting language that compiles to C via kcc. The bundled kcc.exe is all you need to recompile from source. Native Win32 helpers live in kfetch_api.h and are included inline at compile time.
