Install 9xchat
Download and open the current 9xchat build for your platform.
Use the official 9xchat download page to see the builds currently available for your device.
Desktop
- Download the package for Windows, macOS, or Linux.
- Open the package and follow the operating system prompts.
- Launch 9xchat.
- On the first screen, save the UID it shows you, or continue with one you already use.
Windows
You can use the Microsoft Store build or the installer linked from the download page. Launch 9xchat from the Start menu after installation.
The desktop build is code-signed, so Windows should not warn you about an unknown publisher. If SmartScreen appears anyway, choose More info → Run anyway.
macOS
Open the downloaded package, move 9xchat into Applications when prompted, then launch it from Applications or Spotlight.
Linux
Download the Linux package shown on the download page. If your distribution requires it, mark the downloaded file executable before opening it.
Mobile
9xchat ships on Android through Google Play and on iOS through the App Store. Install it, then open the app once it finishes.
Availability can differ by release and region, and the download page is the source of truth for the builds currently offered.
Next step
Continue with your 123sudo UID. The same UID identifies your account and licence across supported 123sudo apps, and 9xchat shows it to you on first run — save it before going further, because it cannot be recovered.
