Built on Linux.
Sara OS uses Arch Linux, the labwc Wayland compositor and GTK for its built-in applications. System components are updated through package repositories; Sara OS releases are digitally signed.
A restore point is created before a system update. The firewall restricts incoming connections by default. Keep a separate backup of your personal files.
Learn about updatesAbout 850 MB for the idle system.
Sara OS is designed as a lightweight desktop. In our test installation, the running system used approximately 850 MB of RAM after sign-in, including the Linux kernel, desktop and background services.
Browsers, applications and Sara AI use additional memory. We recommend 8 GB of RAM for everyday use and 16 GB for Sara AI.
How was this measured?
Measured on 31 October 2026 using Sara OS 1.2.7 in QEMU/KVM: 4 virtual CPUs, 4 GB of RAM and standard virtual graphics. The system was rebooted after installation. No browser, foreground applications or AI model was running.
Three samples were taken 20 seconds apart. RAM use was calculated as MemTotal − MemAvailable from /proc/meminfo, which accounts for memory the kernel can reclaim. Results were 828,186,624, 848,359,424 and 849,616,896 bytes, rounded to approximately 850 MB. Hardware, display settings, drivers and services affect memory use.
