postmarketOS is a free and open-source Linux distribution specifically designed to extend the life of mobile devices and other consumer electronics. It aims to provide a sustainable alternative to traditional mobile operating systems by giving users full control over their hardware.

The main features of this tool include:

• Sustainability and Device Longevity: The project focuses on extending the usefulness of phones and tablets until they physically break, overcoming artificial limits often imposed by a lack of software updates or closed-source components.

• Universal Architecture: Unlike traditional mobile OSs that use device-specific code, postmarketOS utilizes many shared components designed to run across a wide range of hardware.

• Privacy-First Approach: It is designed to act in the interest of the user, explicitly avoiding targeted advertising and the "privacy nightmares" often built into mainstream operating systems from major tech corporations.

• Flexible User Interfaces: The platform supports a variety of mobile-friendly interfaces, including GNOME, KDE, Phosh, and Sxmo, allowing users to choose the environment that best fits their needs.

• Robust Linux Foundation: It is based directly on Alpine Linux and utilizes the mainline Linux kernel, integrating essential libraries and daemons like ModemManager to ensure mobile functionality.

• Upstream Contribution: The project does not just use existing software; it actively contributes hardware enablement and touchscreen optimizations back to the original open-source projects (upstream), helping the entire Linux mobile ecosystem excel.

• Full Transparency: Because the source code is open, users can verify how the system handles their data and ensures their privacy.
