Awesome FLOSS Mobile


We have many operating systems, apps and hardware projects, trying to push for a free/libre/open source mobile device. This page attempts to compile all these projects, state the project goals, and to give a real world review. With this you will know what to throw your support behind.


Core Android Apps

These apps intend to replace the "core" system apps that any user would expect. These download/update apps and provide APIs for apps to use.

  • F-Droid - Repository and app containing only FLOSS software. Has a decent selection. Also check out the Privileged Extension if you are root, so you can install and remove apps in the background without having to confirm.
  • microG - FLOSS reimplementation of the Google Play Services middleware, a must have if you intend to run most Google Play Apps. (hard to install, you should use a pre-configured custom rom instead).
  • Yalp Store - Grabs APKs directly from Google Play and facilitates updates.

Android Forks

The Android Open Source Project is licenced under Apache 2.0. However most versions ship with the proprietary Google Play Services ingrained into the OS. Which harms the user.

  • LineageOS - A fork of Android with it's own set of default apps and extra features. G-Apps are optional and should be avoided if can.
  • LineageOS with microG - This fork of LineageOS is pre-configured with microG and F-Droid with the privilege extension.
  • eelo (beta) - New project from a veteran open-source developer/supporter, huge emphasis on privacy and control and attractiveness. It comes with microG, new default apps, account manager, new search engine and online "cloud" services.
  • Replicant - A fully FLOSS Android OS, that runs absolutely no proprietary firmware/drivers/microcode. Uses F-Droid as it's app store and is approved by the FSF. Only runs on (very) old phones.

Free Hardware Projects

Although a fully free SoC is unlikely, There are hardware projects which intend to make everything as free/open as they can. This usually means it will either let you freely install what ever OS, or that it allows hacking (they may even release schematics), or that it runs with a fully free operating system.

  • ZeroPhone - A work-in-progress open source, Linux-powered, $50 smartphone. Based on the Raspberry Pi Zero, ESP8266 and Arduino.
  • Librem 5 - A work-in-progress premium smartphone that is intended to respect security, privacy and freedom.
