snapFlatpakAppImage
SnapFlatpakAppImage is a proposed cross-compatibility packaging concept that seeks to unify Snap, Flatpak, and AppImage ecosystems into a single workflow for distributing Linux applications. Rather than replacing the individual formats, the idea is to provide a common manifest and build process that can be translated into the target formats and launched on hosts that support any of them.
Design and workflow: Developers write a universal manifest describing app metadata, files, permissions, and runtime requirements.
Status and challenges: As of now, SnapFlatpakAppImage remains an experimental concept rather than an officially supported
