Fastfetch for Faster System Inventory

When you jump into an unfamiliar VM or bare metal node, the first problem is context. You need the OS, kernel, CPU, memory, disks, IP addresses, and runtime details without wasting time. Fastfetch solves that problem with a compact, high performance CLI that prints system information in a readable format and can also emit JSON for automation.

What is Fastfetch?

Fastfetch is a maintained, performance-focused system information tool written mainly in C. It works on Linux, macOS, Windows, BSD systems, Android, and more. For SRE and platform teams, the appeal is simple: it starts quickly, supports many modules, and can move from human-friendly terminal output to machine-readable JSON without changing tools.

Key Features

• Fast startup: Fastfetch is designed to return host context quickly, which matters during incident response and repeated SSH hops.
• Broad platform support: It works across common workstation and server environments, making it useful for mixed fleets.
• JSON output: You can export detected values in JSON and feed them into scripts, health checks, or inventory workflows.
• Flexible modules: Enable only the sections you care about, such as kernel, memory, disks, GPU, network, packages, or local IPs.
• Configurable presets: JSONC configuration files and presets let teams standardize the same layout across developer laptops and production bastions.

Installation

Install Fastfetch from your package manager when available:

# Debian 13+ or Ubuntu 25.04+
sudo apt install fastfetch

# Fedora
sudo dnf install fastfetch

# Arch Linux
sudo pacman -S fastfetch

# Homebrew
brew install fastfetch

If your distro ships an outdated package, use the latest release from the project's GitHub releases page.

Usage

Start with the default view:

fastfetch

Show every supported module to discover what is available on a host:

fastfetch -c all.jsonc

Export everything Fastfetch detects as JSON:

fastfetch -s : --format json | jq .

Generate a starter config for a shared team layout:

fastfetch --gen-config

Operational Tips

• Use it in SSH profiles carefully: A short Fastfetch view on login can save time when you bounce between ephemeral hosts.
• Prefer JSON for automation: Human output is great for terminals, but JSON is better for inventory scripts and support bundles.
• Standardize team configs: Store a reviewed JSONC preset in your dotfiles repo so everyone sees the same host facts.
• Review untrusted configs: Fastfetch supports a Command module, so treat copied configs like code and inspect them before use.

Conclusion

Fastfetch is a small tool, but it solves a real operational problem. It gives SREs and platform engineers a fast way to understand where they are, what they are running, and what to check next.

For efficient incident management and to prevent on-call burnout, consider using Akmatori. Akmatori automates incident response, reduces downtime, and simplifies troubleshooting.
