Fastfetch

Fastfetch is a neofetch-like tool for fetching system information and displaying them in a pretty way. It is written mainly in C, with performance and customizability in mind. Currently, Linux, Android, FreeBSD, MacOS and Windows 7+ are supported.

There are screenshots on different platforms

Installation

Linux

Some distros packaged an outdated fastfetch version. Older version is not supported, please always ensure that the latest version is used.

• Ubuntu: ppa:zhangsongcui3371/fastfetch (for Ubuntu 22.04 or newer)
• Debian / Ubuntu: Download fastfetch-linux-<proper architecture>.deb from Github release page and double-click it (for Ubuntu 20.04 or newer and Debian 11 or newer).
• Arch Linux: sudo pacman -S fastfetch
• Fedora: sudo dnf install fastfetch
• Gentoo: sudo emerge --ask app-misc/fastfetch
• Alpine: apk add --upgrade fastfetch
• NixOS: nix-shell -p fastfetch
• openSUSE: sudo zypper install fastfetch
• ALT Linux: sudo apt-get install fastfetch

Replace sudo with doas depending on what you use.

See also if fastfetch has been packaged for your favorite Linux distro.

If fastfetch is not packaged for your distro or an outdated version is packaged, linuxbrew is a good alternate: brew install fastfetch

macOS

...via HomeBrew:

brew install fastfetch

...via MacPorts:

sudo port install fastfetch

Windows

scoop install fastfetch

You may also download it directly from GitHub releases page and extract the archive.

FreeBSD

pkg install fastfetch

Android (Termux)

pkg install fastfetch

Build from source

See Wiki: https://github.com/fastfetch-cli/fastfetch/wiki/Building

Usage

• Run it with default configuration: fastfetch
• Run it with all supported modules and find what you interest: fastfetch -c all.jsonc
• Find all data that fastfetch detects: fastfetch -s <module> --format json
• Display help messages: fastfetch --help
• Generate config file based on command line arguments: fastfetch --arg1 --arg2 --gen-config

Customization

Fastfetch uses the JSONC (or JSON with comments) for configuration. See Wiki for detail. There are some premade config files in presets, including the ones used for the screenshots above. You can load them using -c <filename>. They may also serve as a good example for format arguments.

Logos can be heavily customized too; see the logo documentation for more information.

Packaging

Repositories

Manual

• DEB / RPM package: cmake --build . --target package
• Install directly: cmake --install . --prefix /usr/local

FAQ

Q: Neofetch is good enough. Why do I need fastfetch?

1. Fastfetch is actively maintained.
2. Fastfetch is faster. As the name suggests.
3. Fastfetch is more feature-rich. By default fastfetch only has a few modules enabled. Use fastfetch -c all to find what you want.
4. Fastfetch is more configurable. You can find more information in the Wiki: https://github.com/fastfetch-cli/fastfetch/wiki/Configuration
5. Fastfetch is more polished. For example, neofetch prints 555MiB in Memory module and 23G in Disk module (notibily the difference of MiB and G), while fastfetch prints 555.00 MiB and 22.97 GiB respectively.
6. Fastfetch is more accurate. For example, neofetch never actually supports Wayland protocol.

Q: Fastfetch shows my local IP address. It leaks my privacy!

A local IP (10.x.x.x, 172.x.x.x, 192.168.x.x) has nothing to do with privacy. It only makes sense if you are on the same network, for example, if you connect to the same Wi-Fi network.

Actually the Local IP module is the most useful module for me personally. I (@CarterLi) have several VMs installed to test fastfetch and often need to SSH into them. I have fastfetch running on shell startup and I never need to type ip addr manually.

If you really don't like it, you can disable the Local IP module in config.jsonc.

Q: Where is the config file? I can't find it.

Fastfetch don't generate config file automatically. You can use fastfetch --gen-config to generate one. The config file will be saved in ~/.config/fastfetch/config.jsonc by default. See Wiki for detail.

Q: The configuration is so complex. Where is the documentation?

Fastfetch uses JSON (with comments) for configuration. I suggest you use an IDE with JSON schema support (like VSCode) to edit it.

Alternatively, you can refer to the presets in presets directory.

Q: I WANT THE DOCUMENTATION!

Here is the documentation. It is generated from JSON schema but you won't like it.

Q: How can I customize the module output?

Fastfetch uses format to generate output. For example to make GPU module show GPU name only and ignore other information, you can use

{
    "modules": [
        {
            "type": "gpu",
            "format": "{2}" // See `fastfetch -h gpu-format` for detail
        }
    ]
}

which is equivalent to fastfetch -s gpu --gpu-format '{2}'

See fastfetch -h format for basic usage. For module specific formattion, see fastfetch -h <module>-format

Q: I have my own ascii-art / image file. How can I show it with fastfetch?

Try fastfetch -l /path/to/logo. See logo documentation for detail.

Q: I want feature A / B / C. Will fastfetch support it?

Fastfetch is a system information tool. We only accept hardware or system level software feature requests. For most personal uses, I recommend using Command module to detect it yourself, which can be used to grab output from a custom shell script:

// This module shows the default editor
{
    "modules": [
        {
            "type": "command",
            "text": "$EDITOR --version | head -1",
            "key": "Editor"
        }
    ]
}

Otherwise, open a feature request in GitHub Issues.
