zfetch

A fast, modern system information tool written in Zig. Similar to neofetch and fastfetch, but built with Zig for maximum performance and minimal dependencies.

Features

• Fast: Written in Zig, compiles to native code with no runtime dependencies
• Cross-platform: Supports Linux, macOS, and Windows
• Comprehensive: Displays OS, kernel, uptime, packages, shell, terminal, DE/WM, CPU, GPU, memory, disk, IP, battery, and more
• Customizable: CLI flags to hide logo, disable colors, or suppress timing
• Colorful: OS-specific ASCII art logos with ANSI color support

Installation

From Source

Requires Zig 0.14.0 or later.

# Clone the repository
git clone https://github.com/santosr2/zfetch.git
cd zfetch

# Build
zig build -Doptimize=ReleaseFast

# Install to ~/.local/bin (optional)
cp zig-out/bin/zfetch ~/.local/bin/

Using mise

If you have mise installed:

git clone https://github.com/santosr2/zfetch.git
cd zfetch
mise install
zig build -Doptimize=ReleaseFast

Usage

# Show system information with logo and colors
zfetch

# Hide the ASCII logo
zfetch --no-logo

# Disable colored output (useful for piping)
zfetch --no-colors

# Hide execution timing
zfetch --no-timing

# Show help
zfetch --help

# Show version
zfetch --version
