skfetch is a lightweight and fast system information tool written in pure C99. It works on Linux, macOS, and *BSD, following the strict Suckless philosophy and Unix way.

Performance

skfetch achieves the fastest possible speed for a compiled binary when running bash commands.

Fetch Tool	Command	Weight	Execution Time
fastfetch-cli/fastfetch	time fastfetch	~1.5MB	0.017s
DylanAraps/pfetch	time pfetch	~59KB	0.031s
b0nn133/skfetch	time skfetch	~25KB	0.062s
DylanAraps/neofetch	time neofetch	~377KB	0.432s
KittyKatt/screenFetch	time screenfetch	~259KB	0.930s

The benchmarks were carried out using the same configuration for all tools (excluding pfetch). Although fastfetch is quicker thanks to its native C/C++ API implementations, skfetch keeps high performance at the same time being ultra-lightweight and transparent in the configuration part through simple C macros and shell commands.

Philosophy

• Zero Bloat: There are no dependencies. The tool compiles into a small binary using native system APIs (uname, sysctl).
• Header-Only Configuration: Configuration occurs entirely at compile time through config.h. There is no slow, runtime JSON or TOML parsing.
• Do One Thing Well: It fetches essential system info. You can easily extend its functionality for memory, packages, or hardware using shell commands without adding bloat.
• Inline Color Coding: Logos use raw custom \1, \2, etc. inline control bytes to manage colors dynamically. This allows for perfect column alignment without string parsing.

Configuration

skfetch follows a traditional suckless compilation setup. Modify config.h:

#ifndef CONFIG_H
#define CONFIG_H

#include "skfetch.h"
#include <stdlib.h>
#include "colors.h"

#define DEF_COLOR        ANSI_CYAN
#define TEXT_COLOR       ANSI_RESET
#define COLOR_CONTROL    ANSI_BOLD

#define FORCE_LOGO       NULL
#define LOGO_ASCII       NULL
#define LOGO_ASCII_PATH  NULL
#define LOGO_COLORS      ANSI_RED, ANSI_GREEN, ANSI_BLUE

static const SKModule enabled_modules[] = {
    { "",       get_user_host, NULL },
    { "",       get_raw_text,  "-----------------" },
    { "OS",     get_os,        NULL },
    { "Kernel", get_kernel,    NULL },
    { "Uptime", get_uptime,    NULL },
};

#endif // CONFIG_H
