What is the smallest OS you know of, with a GUI, VPN client and a web browser? The best I have found so far is Puppy Linux, but can I go smaller?

This question came from our site for professional and enthusiast programmers.


DSL (Damn Small Linux) with the window manager of your choice (E17?).

E17 (formerly known as Enlightenment) is a very slick and stylish and nonetheless lightweight window manager.


The smallest operating system for the PC architecture i know of is MenuetOS (http://www.menuetos.net). It's written completly in x86 assembler and includes a TCP/IP stack, the assembler toolchain and a web browser. It fits on a single disc image. But it lacks the VPN feature, so you have to write it yourself in asm or try using something like hamachi as workaround.

    well, hamachi would need to have support for the OS... so.. not likely it'll work – Journeyman Geek Sep 22 '09 at 10:55

Smallest OS I know is KolibriOS

It's about 1.4 MB (floppy disk size) and features a GUI.

  • Does not feature a VPN client (yet) and only text-based web browser. – gertvdijk Dec 7 '12 at 0:43
