— means: not out yet. Sizes appear when the files exist. Download counts start at zero with the release. Only real people count: downloads by bots are filtered out.

You cannot install the alpha

Alpha 0.1 only runs inside AstraOS Starter: a small program that opens AstraOS in a window on your computer. Nothing gets installed and nothing on your computer changes. Before the first start, the Starter asks whether AstraOS may count anonymously that it is being used.

From the beta: install it

With the beta (1 December 2026), AstraOS Starter becomes Astra Install Helper. Then you can install AstraOS on your PC or put it on a USB stick for another PC. More on the Starter page.

What you need

Is my download the real one?

Download AstraOS only from astraos.page. With the release we will show a check number (SHA-256) next to every file. With it you can check that your file is exactly the one we published.

Parts from others

AstraOS is our own system. A few small parts come from others. We name them and follow their licences:

Versions

Pre-alpha is what exists today. Alpha 0.1 comes on 10 November 2026, the beta on 1 December 2026. Version 1.0 only comes when all three goals are met: apps from Windows, Linux and macOS run directly, the system is proven secure, and every app runs on normal PCs and on ARM computers. Dates can move – we will tell you honestly. See versions and dates.
