Astraea is not developed by or affiliated with HoYoverse. Use it at your own risk. You are responsible for ensuring your use complies with the game’s terms of service and your local law.
Astraea is a launcher for playing Honkai: Star Rail on private servers. If you already have a beta version of the game and your own private server, Astraea launches those builds for you instead of making you patch and configure them by hand.

Download Astraea for Windows

Astraea.Setup.exe – Windows 11
The launcher is only the launcher. Astraea does not include Honkai: Star Rail and does not include a private server. You supply your own beta client and your own server. Astraea will not download, bundle, or set up either one.

​

​
Required
