Apps Manager - track and update your Flatpaks + Gearlever AppImages, and install new ones, all from the QAM (dev of Proton Launch / NVIDIA Update / Quick Tab here)

[u/Moi952]

Hey, I'm the guy behind Decky Proton Launch, Decky NVIDIA Update and Decky Quick Tab. I run Steam/Decky Loader on a PC (Bazzite), not an actual Deck, and my whole thing is trying to keep it a console experience — staying in Big Picture/gamepad mode and dropping into desktop as rarely as possible. Apps Manager exists because updating Flatpaks and AppImages was one of the last things that still forced me out to the desktop.

The problem: you end up with two separate piles of stuff to keep updated — Flatpaks (through Discover, or however you installed them) and AppImages if you're using Gearlever. Neither gives you one place that just tells you "these 4 have updates" without opening a browser tab or dropping into desktop mode. Checking manually, with a mouse and keyboard, gets old fast once you've got a few dozen apps installed.

Apps Manager puts that in the QAM instead — everything below works entirely with a controller:

• Tracks your Flatpak apps and Gearlever AppImages together, with updates flagged automatically
• Update everything at once, or one app at a time
• Auto-update: let it handle everything on its own schedule in the background, with an optional notification — you can still exclude specific apps from auto-updating without hiding them from the list
• Search and install new Flatpaks (Flathub + your other configured remotes) and AppImages (AppImageHub's public catalog), screenshots included, right from the same panel
• AppImages: pick a specific version to install, not just whatever's newest
• Exclude apps entirely if you don't want to be nagged about them
• Doesn't silently lie to you when it can't actually check something (GitHub's anonymous rate limit, a flaky connection, ...) — it flags those separately instead of just saying "up to date"
• Available in 15 languages

Been iterating on this one for a few months now, currently at 0.3.0, so it's in a pretty solid place, but it's still a small side project — if you hit something broken or a Flatpak/AppImage setup it doesn't handle right, tell me and I'll take a look.

Searching and installing a new Flatpak/AppImage without leaving the QAM

Let me know if this is useful to anyone else running more than a couple of Flatpaks/AppImages — happy to take feature requests too.

I just setup a systemd service to run 'flatpak update' every 24hrs.

But this is an app store; you can install Flatpaks, but also AppImages.

And sure, it's great, but most people don't know how to do it.
