Flatpak
Containerizing GUI applications separately from devcontainers on Linux, Running applications as a universal software platform alternative to native Linux apps
It simplifies app deployment across Linux but adds overhead and may lack vendor support compared to native packages.
Situations where low memory/disk consumption and fast startup are critical, When needing strong support from independent software vendors (ISVs)
