PureOS GNU/Linux (or "LiGNUx") is a distribution built on 100% free software. It's based on Debian and is a distro that's highy focused on privacy and security. For other most popular Linux distributions please visit our dedicated linux download page.
PureOS uses Purebrowser, which is based on Firefox and developed to follow PureOS's privacy goals. It uses the DuckDuckGo search engine by default, which doesn't track user data. PureOS also comes with many other enhanced security features enabled by default, such as the HTTPS Everywhere extension that encrypts your data with unsecure websites.
PureOS uses the GNOME desktop environment by default and only supports 64 bit CPUs. It's listed on GNU's website as one of only a handful of operating systems that contain strictly free software. It's also endorsed by the Free Software Foundation.
PureOS is geared towards home computing. It promotes totally free software and user privacy. If you're an advocate for those ideals, this distro may be a good fit for you. Trisquel LiGNUx is another similar choice that features only free software.
PureOS LiGNUx Release Schedule
PureOS is updated daily with security updates and bug fixes. It's on a rolling release schedule which means there is no end of life or new versions you need to upgrade to. You can just use PureOS' package manager to keep your distro up to date with the latest security and features.
Download PureOS LiGNUx
The PureOS ISO file is available on the official download page. There's only one edition available, so if you want to use a desktop environment other than GNOME, you'll have to install it separately.
The download page also includes instructions for Etcher, which can be used to make a bootable USB stick with the PureOS ISO image.
PureOS is a popular choice because of its Purebrowser and other security enhancements. Users can rest easier knowing that their browsing data is private by default and that they're supporting only non-commercial, non-proprietary software.
