A powerful, intuitive GUI to design, preview and deploy your fastfetch configuration — without touching a single line of JSON.
Fastfetch Configurator is a cross-platform desktop application built with Python and PyQt6 that provides a full graphical interface for managing fastfetch configurations.
Instead of manually editing complex .jsonc files, you can visually design your system info display — with real-time previews, section grouping, color theming, Nerd Font icons, custom modules and much more — and export a ready-to-use configuration in one click.
Create and manage fully customizable sections with drag-and-drop module ordering. Each section supports independent color schemes, tree-mode rendering (├─ └─), closed box framing, and custom icons using Nerd Fonts.
Assign individual ANSI colors to section titles, module values, icons, and progress bar fills. Supports all standard ANSI color codes (31–37, 90) and dynamic automatic color assignment.
Add system information modules organized by category — including System Base, Hardware, Resources, Display & Graphics, Desktop Environment, Terminal & Console, Network & Internet, Peripherals, Multimedia, and Filesystems. Each module includes a descriptive tooltip for easy identification.
A categorized, collapsible tree widget lists every available fastfetch module with human-readable descriptions. Double-click or use the Add button to include them in any section.
Each module can be individually configured with a custom display name, advanced format strings (e.g. {1} / {2}), independent icon color, and — where supported — a visual progress bar (CPU usage, RAM, Swap, Battery, Disk, Brightness, Player).
Switch to the Preview tab to instantly render your current configuration through fastfetch, with full ANSI-to-HTML conversion and dark terminal styling. Nerd Font icons are preserved correctly.
Open the current configuration directly in your native terminal emulator (Konsole, GNOME Terminal, XFCE4 Terminal, Alacritty, Kitty, xterm) to see the exact final output. Supports Linux, Windows (cmd) and macOS (Terminal.app).
Replace the default distro logo with a custom image. The logo position, size (Auto / Small / Hidden), and padding (top, left, right) are fully configurable with live spinbox controls.
Load professional ready-made presets to get started instantly: Cyberpunk (neon colors + boxes), Minimalist (no borders, clean layout), and Mac-Style (elegant and compact). Templates can be loaded at any time without losing previous work (confirmation required).
Export your full configuration as a .jsonc file compatible with fastfetch, or reload any previously saved configuration. An internal $gui_config block preserves all GUI state so your layout can be re-edited at any time.
Enable a toggle to automatically run fastfetch when opening a terminal by injecting a call into your .bashrc or .zshrc. The app detects which shell profile exists and confirms before making any changes.
If fastfetch is not detected on the system, the app offers a one-click installation: using winget on Windows, brew on macOS, or pkexec apt install on Linux — no terminal required.
The interface automatically switches between Spanish and English based on the system locale. All labels, tooltips, dialogs, and messages are fully translated via a lightweight runtime translation engine.
Wrap the entire fastfetch output in a styled global box with optional title text and left/center/right alignment — perfect for a polished, framed terminal aesthetic.
Choose the fill and empty characters for all progress bars (blocks, dots, pipes, arrows…) and their respective ANSI colors — with both static and dynamic automatic color modes.
Pre-built binaries are available for all major platforms — no Python installation required.

python main.pyNote: On Linux,
pkexecis required to install fastfetch via the GUI. On Windows,wingetmust be available.
- Tab 1 — Installation: Check if fastfetch is installed. Install it if needed, and optionally enable auto-launch on terminal start.
- Tab 2 — Configuration: Build your layout by creating sections, adding modules, setting colors, icons, and the logo. Load a template or start from scratch.
- Tab 3 — Preview: Render a live HTML preview inside the app, or launch your native terminal for the real output.
Export your config with Generate and Save config.jsonc and you're done.
