What are differences between GearLever and AppManager

[EngineerGlitch]

I noticed the two looks similar, what are the differences ?

You can install it and find out yourself since both apps are not exclusive to each other, but since you asked:

AppManager vs GearLever

AppManager pholosophy is download-install-and-forget, the same way apps are managed by Android or iOS with minimal user involvment.

The core difference

AppManager is a single, self-contained program. You download one file and run it. It does not rely on anything else being set up first, and it works on almost any Linux system, including older ones.

GearLever is a Flatpak-only app. This means GearLever needs the Flatpak system and its runtime installed before it can run at all. The upside is stronger isolation; the downside is the extra dependency and total increased size due to runtime. Additionally it requires python environment installed as a second runtime.

	AppManager	GearLever
Language	Vala (~94%), compiled to a native binary	Python (~98%), interpreted via PyGObject
Toolkit	GTK4 / Libadwaita	GTK4 / Libadwaita
Execution model	Native machine code, no language runtime needed	Python interpreter running inside the GNOME Flatpak runtime
Runtime dependency	None (self-contained binary)	Hard dependency on Flatpak + GNOME runtime
Config storage	GSettings + custom.json for per-app custom values	GSettings
Sandboxed for safety	No	Yes

Everything below follows from this split.

Updates

AppManager can update apps automatically in the background, and it only downloads the parts of an app that actually changed (zsync), which saves time and data. It also self udpates the same way.

GearLever checks for updates in the background and notifies you, but you finish the update yourself. It downloads the whole app each time. Its standout trick is that it can keep older versions installed alongside the new one, instead of replacing them.

---

Files and settings

AppManager keeps your apps in a tidy folder and remembers any changes you make to an app (like custom settings) so they survive future updates. You can also remove an app just by deleting it from the folder, or with a right-click option.

GearLever keeps apps in its own folder too, but it renames the app file on every update. That keeps versions separate, but it can break shortcuts or scripts that point to a fixed file, and your manual tweaks may not carry over after an update.

Feature comparison

Legend: O = supported, X = not supported, ~ = partial / with limits

Feature	AppManager	GearLever
True portable mode (.home / .config)	O	X
Custom user edits preserved across updates	O	X
Custom CLI arguments	O	O
Custom environment variables	O	O
Advanced detail editing (icon, WM class, $PATH)	O	X
Per-app update enable/disable	O	~ (via custom URL, more complex)
Permanent delete + undo (trashless systems)	O	X
Real background auto-update (auto-install)	O	~ (background check + notify only)
GitHub token support (API rate limits)	O	X
Grid view	O	X
List view	O	O
Sort by name / size	O	X
Multi .desktop file support	O	X
CLI command support	O	O
Simple uninstall by deleting from folder	O	~ (can orphan entries)
Desktop right-click uninstall action	O	X
Delta / zsync updates	O	X (full re-download)
Keep multiple versions side by side	O	O
DwarFS + SquashFS extraction	O	O
Runs without FUSE / on any distro	O	X (Flatpak sandbox)
Sandboxed isolation	X	O

Bottom line

Two philosophies.

AppManager is the power-user tool: native and dependency-free, runs anywhere without FUSE, efficient zsync delta updates, real background auto-install, and deep per-app control (portable mode, preserved edits, icon/WM-class/$PATH editing, grid view, sorting, multi-desktop, GitHub token).

GearLever is the sandboxed Flatpak only: a larger and more proven install base, isolation by default, and a standout ability to keep multiple versions of an app side by side.
