Choosing a package

Which file should I use?

Windows users normally need the x64 ZIP package. On Linux, Flatpak is the practical choice when updates should be managed through the desktop software centre or the Flatpak command line. The AppImage is useful when a portable file is preferred, while DEB, RPM and Arch packages integrate with their respective package managers.

macOS packages are provided for Apple Silicon and Intel systems on a best-effort basis. They are not currently notarized by Apple. The installation guide covers the first launch, updates, the Stable, Beta and Nightly channels, and the location of the settings directory.

Development and infrastructure

KST4Contest is developed independently. If it is useful in your contest workflow and you want to help cover continued development, testing and infrastructure costs, the support page explains what project contributions are used for.
