AlmaLinux OS vs postmarketOS

AlmaLinux OS is a free, open-source, community-owned enterprise Linux distribution designed for binary compatibility with RHEL. The project presents it as an option for users who need enterprise Linux without a commercial license agreement, including people seeking a CentOS Linux replacement. It can run on servers, workstations, virtual machines, cloud instances, containers, Raspberry Pi devices and Windows Subsystem for Linux environments. ISO downloads cover x86_64, aarch64, ppc64le and s390x architectures. The project also provides cloud images, OCI, Docker and UBI-compatible container images, Vagrant images, and live media with several desktop choices. A WSL image provides a terminal environment on Windows. The Foundation publishes security and bug-fix errata, and packages are GPG-signed and verified by default when installed. OpenSCAP, SCAP Workbench, OVAL streams and CIS tooling are available for auditing or hardening systems. Community support is available through forums, chat and Reddit; commercial support is offered separately by listed providers. The project plans stable updates and security patches for 8.x until 2029 and 9.x until 2032.

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.
