Before release
Three clean boots
The image should boot into the shell repeatedly, not just once after a lucky build.
Download
No OS image yet. That is intentional.
Sky OS is still pre-alpha. A download button would be easy to fake. A build that boots cleanly, explains itself, and does not waste people’s time takes longer.
Current download status
Public alpha planned for mid-2027.
The first public release is planned as a VM/QEMU-friendly preview image with notes, setup steps, and a clear list of what works.
What will be downloadable laterBootable development image, release notes, build instructions, known limitations, and recovery/safety notes.
Why waiting matters
A good alpha should be boring.
For an operating system, “it opened once” is not enough. Before a public image makes sense, Sky OS needs repeatable boot tests, safe file operations, stable shell behavior, desktop entry/exit, and release notes that do not hide the rough parts.
The download page will stay honest: if something is experimental, it will say experimental. If something can break data, it will say that too.
Before release
Desktop opens and returns
The desktop preview should open, respond, and return to the shell without corrupting input.
Before release
Clear release notes
Every preview will explain what works, what is mocked, what is internal-only, and what users should avoid.
Safety note: when the first image arrives, use a virtual machine first. Early OS storage work is not something to test casually on a real disk with important files.
