Astrum overlay

Download the Astrum desktop overlay.

Run Astrum on top of your game so chat is always in view. One identity, one account — your profile, reputation, and overlay chat all live under the same login as the web.

The 0.1 alpha ships first for macOS with a Windows build close behind. While we package the installers, you can still use Chat in the browser and keep your progress.

Expect bugs. Expect changes. What you do here shapes what Astrum becomes.

Windows builds follow shortly after macOS once we finish signing, installers, and launch-day stress testing.

When the builds are ready, the buttons above will switch to direct download links for the latest signed installers (.dmg on macOS and .msi / .exe on Windows).

Until then, you can always use Astrum in the browser at /crossroads/global while we finish packaging the desktop overlay.
