Underrated Raspberry Pi 4 OS Options You Must Try

If you own a Raspberry Pi 4, you’ve probably already tried Raspberry Pi OS, but several underrated operating systems unlock its full potential for specific tasks like retro gaming, media centers, lightweight desktops, and server workloads. This article covers seven lesser-known but excellent OS options, explains what makes each unique, and helps you choose the right one for your project.

Why Look Beyond Raspberry Pi OS?

The official Raspberry Pi OS (formerly Raspbian) is stable and well-supported, but it’s not always the best fit. It can feel heavy on a 2GB Pi 4, lacks built-in features for niche uses, and doesn’t leverage the Pi 4’s hardware acceleration in every scenario. Underrated alternatives often provide:

• Better performance for specific workloads (e.g., gaming, video playback).
• Smaller footprints that free up RAM and storage.
• Specialized tools pre-installed, saving setup time.
• Different user interfaces that suit particular preferences or use cases.

While Raspberry Pi OS remains the safest default, exploring alternatives can dramatically improve your experience for dedicated projects.

1. Manjaro ARM (Arch Linux for Pi)

Manjaro ARM is a rolling-release distribution based on Arch Linux, optimized for ARM devices including the Pi 4. It’s underrated because many users assume Arch is too complex, but Manjaro’s installer and graphical tools make it accessible. You get access to the Arch User Repository (AUR), which has thousands of packages not available in Raspberry Pi OS. The Pi 4 version uses a lightweight XFCE desktop by default, which runs smoothly on 2GB or 4GB models.

Why try it? If you want the latest software versions (kernel, drivers, applications) without waiting for official releases, Manjaro ARM delivers. It also supports multiple kernels (e.g., linux-rpi, linux-rpi-5.15) that you can switch between. However, rolling releases can occasionally break, so it’s better for hobbyists comfortable with basic command-line troubleshooting.

2. DietPi (Ultra-Lightweight Server OS)

DietPi is a Debian-based OS stripped down to the essentials, designed to run on minimal hardware. It’s not just a lighter Raspberry Pi OS—it includes a built-in software optimizer that lets you install pre-configured applications (like Pi-hole, Nextcloud, or Home Assistant) with a single command. The entire system typically uses under 100MB of RAM at idle, leaving more resources for your actual services.

DietPi is ideal for headless server projects where you don’t need a desktop environment. It also has a unique feature: it can automatically reduce CPU frequency scaling and disable unnecessary services to save power. If you’re building a network-wide ad blocker, a file server, or a smart home hub, DietPi is a hidden gem that’s more efficient than the default OS.

3. Lakka (Retro Gaming Console)

Lakka is a lightweight Linux distribution that turns your Pi 4 into a retro gaming console instantly. It’s based on LibreELEC and uses RetroArch as its frontend, supporting dozens of emulators for systems like NES, SNES, PlayStation, and even Nintendo 64 (on Pi 4). What makes it underrated is that it’s not just a collection of emulators—it’s a fully integrated OS where the entire interface is designed for gamepad navigation.

Unlike RetroPie, which runs on top of Raspberry Pi OS, Lakka is a standalone OS that boots directly into RetroArch. This reduces overhead and improves performance. It also supports netplay (online multiplayer) and has built-in shaders for CRT effects. If you want a dedicated retro gaming machine without the bloat of a full desktop OS, Lakka is a top choice.

4. LibreELEC (Kodi Media Center)

LibreELEC is a minimal OS built specifically for Kodi, the popular media center software. While many people use Raspberry Pi OS and install Kodi manually, LibreELEC offers a purpose-built environment that’s faster and more stable. It boots directly into Kodi, uses the Pi 4’s hardware video decoder for smooth 4K playback, and includes automatic updates.

What’s underrated is how well LibreELEC handles audio passthrough (Dolby Atmos, DTS) and HDR content on the Pi 4. It also supports add-ons for streaming services, live TV, and even retro gaming via the Kodi RetroPlayer. If you’re building a dedicated media center, LibreELEC is lighter and more reliable than a general-purpose OS with Kodi installed.

5. Ubuntu Server (for Serious Server Projects)

Ubuntu Server for Raspberry Pi is often overlooked because people assume it’s just a command-line version of the desktop. However, it’s a robust, well-documented OS that’s ideal for running Docker containers, Kubernetes clusters, or web servers. It uses the same kernel as Raspberry Pi OS but offers better support for enterprise tools like snap packages and Canonical’s Livepatch service.

Why is it underrated? Many Pi users don’t realize that Ubuntu Server has official support for 64-bit ARM, which allows you to run modern software that requires 64-bit CPUs. It also has a smaller memory footprint than the desktop version, leaving more room for your applications. If you’re comfortable with the command line, Ubuntu Server is a reliable choice for long-running projects.

6. Twister OS (Windows/macOS Lookalike)

Twister OS is a modified version of Raspberry Pi OS that mimics the look and feel of Windows 10, macOS, or even older Mac OS X. It’s underrated because it’s often dismissed as a gimmick, but it’s actually a fully functional OS with a custom theme engine, pre-installed applications, and support for running Windows software via Wine (though performance varies).

Twister OS includes a “Twister UI� that lets you switch between different desktop themes (like “Windows 11� or “Big Sur�) with a single click. It also has a built-in “Box86� emulator that allows some x86 Linux applications to run on the Pi. If you want a familiar interface for a family member or just enjoy customizing, Twister OS is a fun and surprisingly stable option.

7. Kali Linux (Security Testing)

Kali Linux is a Debian-based OS designed for digital forensics and penetration testing. It’s well-known in the security community but underused on the Pi 4 because people assume it’s too heavy or complex. However, the Pi 4’s quad-core processor and up to 8GB RAM handle Kali’s tools quite well. You can run network scanners, password crackers, and wireless attacks (with compatible USB adapters) directly from your Pi.

Kali on the Pi 4 is a portable, low-cost security testing kit. It boots into a full desktop environment and includes tools like Metasploit, Wireshark, and Aircrack-ng. Be aware that using these tools on networks you don’t own is illegal in most jurisdictions, so only use Kali ethically on your own equipment.

How to Choose the Right OS

Your choice depends on your project goal:

• Retro gaming: Lakka (simplest) or RetroPie (more customizable).
• Media center: LibreELEC (optimized) or OSMC (alternative).
• Server/headless: DietPi (light) or Ubuntu Server (feature-rich).
• Desktop replacement: Manjaro ARM (modern) or Twister OS (familiar UI).
• Security testing: Kali Linux.

Also consider your Pi’s RAM: 2GB is fine for DietPi or Lakka, but 4GB or 8GB is better for Manjaro or Kali with a desktop. Always back up your SD card before switching, and use a microSD card with good read/write speeds (A2 class) for best performance.

Common Problems and How to Fix Them

Switching OSes can bring issues:

• No boot: Ensure you’ve written the image correctly (use Raspberry Pi Imager or BalenaEtcher) and that your power supply delivers 5V/3A.
• Wi-Fi not working: Some OSes need extra firmware; check the official documentation or install the firmware package.
• Overheating: The Pi 4 runs hot; use a heatsink or fan, especially under load.
• Slow performance: Try disabling the desktop environment if you don’t need it, or switch to a lighter OS like DietPi.

If you encounter errors, consult the OS’s official forums—they’re usually active and helpful.

Frequently Asked Questions

Can I dual-boot multiple OSes on a Raspberry Pi 4?

Yes, you can use a tool like PINN (a multi-boot manager) to install several OSes on one SD card. At boot, you’ll see a menu to choose which OS to start. However, this uses more storage and can complicate updates. It’s simpler to keep separate SD cards for different projects.

Which OS is fastest for the Raspberry Pi 4?

For lightweight tasks, DietPi is the fastest because it runs with minimal background processes. For desktop use, Manjaro ARM with XFCE is snappier than Raspberry Pi OS due to its lighter interface. For gaming, Lakka is optimized for emulation performance.

Do these OSes support the Pi 4’s 64-bit processor?

Most modern ones do. Raspberry Pi OS has a 64-bit version, and all the OSes listed here offer 64-bit builds except Twister OS (which is 32-bit but works fine). 64-bit allows you to run more software and use more than 4GB RAM effectively.

Can I use these OSes on a Raspberry Pi 3 or 5?

Most are compatible with Pi 3 (though slower) and Pi 5 (with some caveats). Check each OS’s official download page for supported models. For Pi 5, you’ll need OSes that have updated their kernels to support the new hardware.

Is it safe to overclock my Pi 4 with these OSes?

Overclocking is possible in some OSes (e.g., via config.txt), but it increases heat and power draw. It’s safe if you have proper cooling, but it can reduce the lifespan of the chip. Only overclock if you need extra performance and understand the risks.

Which OS is best for beginners?

Raspberry Pi OS is still the most beginner-friendly. Among the underrated options, DietPi is easy for server tasks because it automates setup, and Lakka is simple for gaming—just burn and boot. Twister OS is also user-friendly if you want a familiar desktop look.
