postmarketOS vs PureOS

postmarketOS, now called Nura, is a free, open-source operating system project focused on extending the life of consumer electronics. Its listed latest stable release is Nura v26.06; development builds are labeled edge. The project says users can customize the system, install software, and choose when to update, and describes privacy and user control as goals. Nura is based directly on Alpine Linux and uses Linux mobile components including ModemManager. Interface options include GNOME, KDE, Phosh, and Sxmo. Install images are listed for phones, tablets, Chromebooks, laptops, single-board computers, and x86_64 EFI systems, with support varying by device category. Listed architectures are aarch64, armv7, x86_64, and riscv64. The install page says listed images use close-to-mainline kernels. Stable and edge channels are available, and stable kernel packages are kept current while a release is supported. Device support depends on its category and maintainers; community and testing devices may lack features, have limited functionality, or receive limited maintenance. The project notes usability and stability issues remain and advises against Nura for those seeking an operating system as usable as iOS or Android. It has no support contract; community members may help when available. Installation guidance and a Matrix/IRC channel are linked for questions. The operating system formerly known as postmarketOS was renamed Nura in an announcement on September 27, 2026. The plan costs nothing.
