Fastfetch

Fastfetch is a neofetch-like tool for fetching system information and displaying it in a visually appealing way. It is written mainly in C, with a focus on performance and customizability. Currently, it supports Linux, macOS, Windows 8.1+, Android, FreeBSD, OpenBSD, NetBSD, DragonFly, Haiku and SunOS (illumos, Solaris).

Note: Fastfetch is only actively tested on x86-64 and aarch64 platforms. It may work on other platforms but is not guaranteed to do so.

Build from source

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

Usage

• Run with default configuration: fastfetch
• Run with all supported modules to find what interests you: fastfetch -c all.jsonc
• View all data that fastfetch detects: fastfetch -s <module1>[:<module2>][:<module3>] --format json
• Display help messages: fastfetch --help
• Generate a minimal config file: fastfetch [-s <module1>[:<module2>]] --gen-config [</path/to/config.jsonc>]
  • Use: --gen-config-full to generate a full config file with all optional options

Customization

Fastfetch uses JSONC (JSON with comments) for configuration. See the Wiki for details. There are some premade config files in the presets directory, including those used for the screenshots above. You can load them using -c <filename>. These files can serve as examples of the configuration syntax.

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

WARNING

Fastfetch supports a Command module that can run arbitrary shell commands. If you copy-paste a config file from an untrusted source, it may contain malicious commands that can harm your system or compromise your privacy. Please always review the config file before using it.

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 has a greater number of features, though by default it only has a few modules enabled; use fastfetch -c all to discover 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 555 MiB in the Memory module and 23 G in the Disk module, whereas fastfetch prints 555.00 MiB and 22.97 GiB respectively.
6. Fastfetch is more accurate. For example, neofetch never actually supports the Wayland protocol.

Q: Fastfetch shows my local IP address. Does it leak my privacy?

A local IP address (10.x.x.x, 172.x.x.x, 192.168.x.x) has nothing to do with privacy. It only has meaning 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. With fastfetch running on shell startup, 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 does not generate a 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 the Wiki for details.

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

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

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

The correct way to edit the configuration:

This is an example that changes size prefix from MiB / GiB to MB / GB. Editor used: helix

Q: I WANT THE DOCUMENTATION!

Here is the documentation. It is generated from the JSON schema, but you might not find it very user-friendly.
