Client

There are two ways to connect to Cosmic Reborn for the most optimal experience. Choose the option that suits you best.

Recommended

Option A

Reborn Launcher

Our custom launcher built on top of Cosmic Client, with extra features and quality-of-life improvements.

  • In-Game Voice ChatNew
  • Connect using .com or .net or .orgNew
  • Built-in Account Manager
  • Bug fixes and miscellaneous improvements

Supported platforms: Windows and Linux only. macOS is not currently supported.

Note: Because the Reborn Launcher is newer and less widely downloaded, Windows SmartScreen may show a warning. This is expected - click More info, then Run anyway.

Windows Linux macOS 

Option B

Official Cosmic Client

Use the official Cosmic Client if you need support for Mac, or just prefer the original experience.

Available from cosmicclient.com.

Supported platforms: Windows, Linux, and macOS.

Important: You must connect using .com with the official Cosmic Client. The .net or .org addresses will not work.

The Cosmic Client will likely sunset in the near future, so we recommend Option A for a more future-proof experience.
