Open where it matters.
coreboot firmware, Intel ME disabled, and model-specific firmware controls make the invisible layers inspectable.
StarBook Horizon
The Linux laptop
you actually own.
Horizon is the current StarBook variant: a refined 13.4-inch portable with open firmware, native Linux support, privacy hardware, and serviceable parts.
From $2,554.00
Free shipping to most regions.
Yours from first boot.
Ships with a clean distro image that completes setup when you turn it on. No factory password, no hidden encryption secret, and no Star Labs driver package.
Serviceable by design.
The battery and SSD are accessible, firmware is updated through LVFS, and compatible parts can carry forward.
Private by hardware. Open by design.
Horizon combines physical privacy controls, Linux-first firmware, and long-term ownership in one machine.
Privacy reaches firmware.
Privacy screen, kill switch, webcam cover, and Intel ME disabled.
Clean setup. Standard Linux.
Create your own account and encryption choices on first boot. Want another distro later? Use its standard ISO with Linux 6.2 or later.
Kept useful longer.
Replace the battery, swap the SSD, and upgrade compatible parts across generations instead of replacing the whole machine.
Measured on Linux.
Published Ubuntu results, idle battery context, and storage security details keep the performance story concrete.

Core specs at a glance.
The basics buyers ask for first: display, weight, processor, memory, and battery.
Quiet when you want it.
Horizon exposes cooling control in firmware. Choose silence for lighter work, then switch active cooling back on when sustained workloads need it.

Premium where it matters.
The premium choices are concentrated where they matter: screen, chassis, storage, input, and security.
Screen and build
Taller display, aluminium body.
13.4-inch 3:2, 90Hz, 500-nit panel in a sand-blasted 6061 aluminium chassis.
Storage and input

Security
Security built into the stack.

Built to feel refined, not flashy.
Horizon is a deliberate portable: taller than a typical widescreen laptop, lighter than a workstation, and built around privacy-first hardware.
