Sysfetchme is an ultra-lightweight, zero-fork system information tool written in pure standard C. Engineered from the ground up for sub-millisecond execution, it retrieves telemetry directly via kernel interfaces and memory mappings—completely bypassing heavy shell spawns (awk, sed, grep, wmic) and runtime dynamic library lookups (dlopen).
Whether integrated into your interactive shell, server MOTD, tmux status line, or CI/CD pipelines, Sysfetchme delivers instant hardware and software metrics with zero lag.

sysfetchme --brief / -b)> Compact, distraction-free summary focusing only on primary computing metrics.
sysfetchme --balanced / default sysfetchme)> Comprehensive everyday overview for daily terminal sessions.
sysfetchme --detailed / -d)> Exhaustive hardware suite for hardware verification and power users.

Sysfetchme comes with curated 24-bit TrueColor themes designed for modern terminal color schemes:
sysfetchme --theme cyberpunk # Neon Cyan & Hot Magenta
sysfetchme --theme nord # Arctic Blue & Frost Teal
sysfetchme --theme dracula # Vampire Purple & Toxic Green
sysfetchme --theme catppuccin # Pastel Latte / Mocha Tones
sysfetchme --theme gruvbox # Warm Retro Earthy Gold
Enable or disable automatic execution when opening new terminal sessions with built-in controller flags:
# Enable auto-start for CMD and PowerShell
sysfetchme --on
# Disable auto-start anytime
sysfetchme --off
Pass --json to stream structured telemetry in < 0.2ms for status bars (Polybar, Waybar, Rainmeter, tmux):
