What started as a side project by a college undergrad, turned into a full-fledged revolution in the operating system segment. The inspiration behind Linux was the Minx, a Unix-based operating system.

Unix-like(or *nix) was gaining momentum around the same time when Microsoft was beginning to make waves in the desktop computer segment with its Windows NT family of operating systems.

Today, Linux is used worldwide for embedded computers to power virtually all the supercomputers that are currently in function.

If you want to use Linux on an old PC or laptop that has an outdated hardware configuration you may want to look for the best lightweight Linux distributions.

Moreover, lightweight Linux distros are also good for beginners to play with and learn.

Best Lightweight Linux Distros

Lightweight may be relative for users but it generally covers computers with modest configuration, and consequently less resource usage.

We have shortlisted the best Lightweight Linux distros that you can use in 2023

Just like other lightweight OS, Tiny Core can be installed on virtually all modern flash drives or SD cards. Y

ou can install it directly to RAM as well. While the booting is fast being installed on HDD, it is blazing fast when loaded on RAM.

Users who are looking to use it for Internet surfing will find it Internet-ready, thanks to its swift network card detection.

3. Puppy Linux

Puppy Linux

Puppy Linux was synonymous with distros for low-end computers. 

Unlike other distros, Puppy Linux boots directly into a ramdisk, therefore not requiring physically installed hard disk  

With the passage of time, support for the lightweight distro has toned down. However, it continues to receive support, as Raspberry Pi OS is based on Debian/Puppy Linux.

As the OS is directly loaded into the RAM, it is considerably faster than the others. The functions and opening of programs is prominently swifter. 

The default web browser, Palemooon, has a wide room for customization. Some users have compared it to the modern Firefox in terms of performance and features. 

Minimum requirements for Puppy Linux

  • RAM: 128 MB RAM
  • CPU: Pentium 900 mhz or higher
  • Disk Space: 600 MB

4. antiX

Antix Linux

antiX is a Debian-based LiveCD Linux distro that is fast, lightweight, and easy to use. MX Linux is based on antiX itself.

Alot of users make USB-bootable media for running it directly from the flash drive.
The default desktop environments are IceWM, Fluxbox, and JWM. You can install your favorite DE with help from the official forum, which is a bit of work, to be fair.

Moreover, the F-keys and the boot options are something out of the ordinary. Many users will find it useful.

Talking about resource usage, it leaves minimal resource imprint on your hardware. It uses half the RAM used by the popular MX Linux.

Minimum requirements for antX
