blaeckfetch

A fast, minimalist system fetch for your terminal. Written in Rust. Powered by blaeck for rendering.

Blaeckfetch default logo (moon) with essential system info. Customize as you like:

logo = "arch"
fields = ["OS", "CPU", "GPU", "Memory", "Disk (/)", "Local IP"]
color = "cyan"
palette = true

[colors]
title = [255, 165, 0]
label = "cyan"
logo = "magenta"

Splash mode

Animated sequence inspired by retro SEGA intro, background image, blinking footer, and collapse exit. Use a custom PNG/JPEG or it will fallback to an ASCII procedural starfield. Press any key to dismiss. Add blaeckfetch --splash to your shell RC for a startup splash.

More modes to come in the future.

Performance

Tool	Time
blaeckfetch	~7ms
neofetch	~400ms

~57x faster than neofetch. Boot-cycle cache keeps static fields instant after the first run.

Terminal compatibility

Works in any terminal that supports ANSI escape codes. Truecolor terminals (iTerm2, WezTerm, Kitty, Ghostty, Alacritty) get full 24-bit RGB. Terminals without truecolor (macOS Terminal.app) automatically fall back to 256-color approximation. VHS recordings are supported with full animation.
