Open Source Mobile OS Alternatives To Android

It’s no exaggeration to say that open source operating systems rule the world of mobile devices. Android is still an open source project, after all.
But, due to the bundle of proprietary software that comes along with Android on consumer devices, many people don’t consider it an open source operating system.

So what are the alternatives to Android? iOS? Maybe, but I am primarily interested in open source alternatives to Android. I am going to list not one, not two, but seven alternative, Linux-based mobile OSes.

Top Open Source alternatives to Android

Let’s see what open source mobile operating systems are available. Just to mention, the list is not in any hierarchical or chronological order.

1. Tizen

Tizen is an open source, Linux based mobile operating system. It is often dubbed an official Linux mobile OS, as the project is supported by the Linux Foundation.

Apart from the Linux Foundation, the Tizen project is supported by tech giants Samsung and Intel. Initially slotted for late 2013 release, it was only in January 2015 that the first Tizen phone, the Samsung Z, was released in the South Asian market. Unfortunately, the Samsung Z failed to get much attention in a competitive Indian market.

Despite being based on Linux, Tizen OS has been marred by security issues. Quite frankly, I don’t see a bright future for Tizen OS. It is just a matter of time before the plug is pulled from this project.

2. Plasma Mobile

A few years back, KDE announced its own open source mobile OS, Plasma Mobile. Plasma Mobile is the mobile version of the desktop Plasma user interface, and aims to provide convergence for KDE users.

The OS is in the development phase and can be tested on a few devices, like LG Nexus 5.

3. PostmarketOS

PostmarketOS (pmOS for short) is a touch-optimized, pre-configured Alpine Linux with its own packages, which can be installed on smartphones.

The idea is to enable a 10-year life cycle for smartphones. You probably already know that, after a few years, Android and iOS stop providing updates for older smartphones. At the same time, you can run Linux on older computers easily. PostmarketOS wants to achieve the same on the mobile platform, by tweaking Linux into a touch-optimized platform.

Don’t get too excited. PostmarketOS is in very early phases of development, and it is most likely that you won’t be able to use it like a regular smartphone yet.

4. PureOS/Librem

Ubuntu’s convergence efforts did not materialize, but this has not deterred others from their convergence dreams.

Convergence, in simple terms, is having the same operating system running on desktops, tablets, and smartphones. Ubuntu tried it and abandoned the project. Windows also failed at it.

The security and privacy focused company Purism has its own PureOS Linux distribution. They are also working on a Linux-based, secure smartphone called Librem5. Purism claims that PureOS is convergent, and Librem smartphones will run it. Apart from PureOS, it can run GNOME and KDE, with Debian, Ubuntu, SUSE, Fedora. and even Arch Linux.

The motto of the Librem is to be a “phone that focuses on security by design and privacy protection by default. Running Free/Libre and Open Source software and a GNU+Linux Operating System designed to create an open development utopia, rather than the walled gardens from all other phone providers”.

It’s more of a Linux-based smartphone rather than a Linux-based smartphone OS, but I believe that the convergent PureOS should be able to run on other devices with some tweaks.

5. Ubuntu Touch by UBports

The king of desktop Linux world, Ubuntu decided to expand its territory with its open source mobile operating system, Ubuntu Touch. Keeping convergence in mind, Canonical (the parent company of Ubuntu) ambitiously launched a $32 million crowdfunding campaign to build the first Ubuntu Phone, Edge. Though it failed to get the desired amount, it still set a new record, with over $12 million pledged to the campaign.

After the failed crowdfunding campaign, Canonical teamed up with some device manufacturers to launch Ubuntu Phone. Spanish manufacturer BQ became the makers of the first device running Ubuntu Touch in February, 2015. It was soon followed by Chinese manufacturer Meizu. Those first few devices were aimed at developers, which is the reason I advised people not to buy the BQ Ubuntu Phone at the time.

Two years and a few Ubuntu-based phones later, Canonical finally decided to call it quits on their mobile OS. However, UBports is still trying to keep Ubuntu Touch alive.

With UBports’ efforts, Ubuntu Touch recently saw OTA 12 update. There are a handful of devices that are supported by Ubuntu Touch. You can see the list here.

6. LuneOS

LuneOS is an open-source mobile OS based on Linux kernel. It may not be a feature-rich alternative to Android (of course!). However, it is the successor to Palm/WebOS.

The last release was at the end of 2018. Since then, there have been no updates to the project so far.

The good thing about LuneOS is – if your device is compatible with CyanogenMod, it will most probably work on LuneOS. It is being maintained by WebOS Ports with no recent updates to it.

Open Source projects based on Android (free from Google)

Most of the above open source mobile operating systems you saw so far are under development and not available for a wide range of mobile hardware.

Don’t despair. There are a few projects that are based on Android but customized to remove Google services from it. These Android distributions are open source and you can customize them to your liking.

If you are looking for an open source alternative to mainstream Android, these projects could be a good choice.


7. LineageOS and Replicant (open source Android distributions)

Both LineageOS and Replicant are open source Android distributions. In other words, you can call them custom ROMs.

LineageOS was created after the much more successful Android distribution CyanogenMod was discontinued. LineageOS is a fork of CyanogenMod.

Though Replicant was founded back in 2010 by a couple of Free Software groups, it now uses the source code of LineageOS as the base. You can see the list of devices supported by Replicant here.

What do you think?


When I first wrote this article a few years ago, I was hopeful for some of these alternative mobile OSes. However, the present situation is gloomy, and I don’t think any OS listed here is going to make a mark. It’s not like I don’t want them to be a success, I am just being honest here.

What do you think of these Android alternatives? Do you think these Linux based mobile OS will leave their mark or will they struggle for a decent market share like desktop Linux? Do share your views.
