The data
appliance
OS.

One Go binary is the whole machine — kernel objects, services, desktop. It serves data on the wire and shows you everything on screen. Plug in a monitor: your server has a face.

Two images, same OS. SeaOS ships the kernel verified on a ThinkPad X1 Carbon. Universal ships a broad driver set for other machines — mini-PCs, 2.5GbE router boards, AMD and Intel boxes. Try Universal if the first one does not reach the boot menu.

SeaCraft ships in the base image and renders on seabox-fb. Go ahead — move with A/D, jump, mine and place blocks. Live, right here.

BUNDLED
Real apps, not demos.
Every app ships in the base image. Keyboard-first, window-managed, hackable from source.
ARCHITECTURE
A microkernel
that gets out of the way.
The kernel exposes objects through handles. Services talk over channels. The syscall layer dispatches to svc, then IPC, then the shell — nothing more in the trusted core.
SPECIFICATIONS
Under the hood.

Boot it in 2 seconds.

Free to download and run. One static binary, yours to build on.
