Supported Platforms 📲

Platform	Format	Download
Android	APK	GitHub Releases
Windows	EXE, MSI	GitHub Releases
Linux	AppImage, DEB, RPM	GitHub Releases

Linux (Arch/Fedora-based distros): If the AppImage crashes with an EGL display error, install the .deb (via debtap) or .rpm (via rpmextract) package instead.

Web: A hosted web version isn't available because OAuth authentication requires a localhost callback, which only works on your own machine. To try Lumi AI in the browser, clone the repo and run bun run dev locally.
