Four official ways to install Stella Sora. The hero button on the home page lands here because there is no browser client to embed.
From the desk. I followed the store links from stellasora.global, the Steam API for app 4813850, Google Play package com.YoStarEN.StellaSora, and App Store id 6738407069. Each one is a Yostar listing. I am not hosting an installer on this site.
Official links
stellasora.global is the global portal. The official download feed currently lists this Windows launcher link. Smart links can redirect by device or region. The roughly 13 GB launch pre-download figure is historical, not a current installed-size measurement.
Steam app 4813850 went live 19 October 2026. Steam reports Windows only, English text, and 20 GB. Details and the requirements table are on PC and Steam.
Google Play and the App Store are the mobile stores. Phone storage advice from the official FAQ is 12 GB free. The iOS download size on 22 October 2026 was 3.49 GB. See Android and iOS.
What is not an official download
There is no official Mac build, no official Linux build, and no official web version. Steam’s API flags macOS and Linux as unsupported. I will not link APK mirrors, emulators or private servers.
One Global account can sync across the Windows launcher, Steam, Android and iOS after you bind email, Google, Facebook or Apple. Steam adds Steam login. Accounts from the JP, KR, CN and TW servers cannot log into Global and cannot transfer, per the 18 October 2026 Steam FAQ on the official news list.
