We are sick of not receiving updates shortly after buying new phones. Sick of the walled gardens deeply integrated into Android and iOS. That's why we are developing a sustainable, privacy and security focused free software mobile OS that is modeled after traditional Linux distributions. With privilege separation in mind. Let's keep our devices useful and safe until they physically break! What is the current state of postmarketOS? Where can I download the latest release? Which devices run postmarketOS? How do I port my device?

postmarketOS is based on Alpine Linux, which is so tiny (less than 10 MB in size) that development of pmOS can be done quickly on any Linux distribution. We install Alpine in multiple chroots to cross compile packages, build and flash postmarketOS, run it in a VM with QEMU or interactively port new hardware. All with our lightweight Python program pmbootstrap, without installing anything on the host system. Writing packages is easy, by the way: as long as you know how to write shell scripts, you are good to go. We have continuous integration in place that makes sure everything builds that gets submitted to our packages repository, among other sanity checks.

The above design decisions make it feasible to keep the system up-to-date, for all devices at once! Compared to Android, it makes development more efficient and democratic: you don't need to afford a powerful and expensive PC to rebuild the entire OS. Just build the tiny part that you are interested in modifying.
