AppManager is a GTK4/Libadwaita app for Ubuntu that installs and manages AppImages without requiring FUSE 2 (libfuse2t64), using uruntime instead. It supports both SquashFS and DwarFS-packed AppImages, offers a macOS-style drag-to-install flow, handles bulk import of existing AppImages, and provides per-app settings for launch arguments, icons, environment variables, and portable home folders. Updates can be scheduled with zsync delta patches, and a CLI is bundled for terminal users. It's open source and distributed as an AppImage itself.
