I have over 3k Steam entries (~2.5k real games). First I opened the Storepage of every single new Game, read the Tags, added every Tag (most of the time I tried to choose the first 10 Tags) to the Game to Categorize it. ~10 times “Add to…” per game. Fun isn’t it?
Then I found Depressurizer which was the only tool that made this bearable - but it’s Windows-only!
Sadly I didn’t manage to run it on Linux. Tried it under different Wine and Bottles setups, nope not for me! (Maybe I’m just to stupid to get it up and running?)
Three months ago I finally quitted Windows and forced myself to use Linux as daily driver! Glad I did it.
And I told myself: Before I start Windows just to sort my game library, let’s start to make one for the Linux Community! Directly on Linux, for Linux!
So I built SteamLibraryManager with PyCharm from scratch on CachyOS.
My App is available as AppImage (good for SteamDeck), AUR, .deb, .rpm, tar.gz:
yay -S steam-library-manager
GitHub: SwitchLibraryManager
What it does (just the highlights - check the GitHub README for the full feature list):
Smart Collections with full Boolean logic (AND/OR/NOT + nested groups) - Steam’s dynamic collections have been AND-only since 2018. So I had the Idea with my own “Dynamic Collections” called “Smart Collections”.
If you like to see a short Video of SLM
Auto-categorize by 17 rule types: Tags, Genres, ProtonDB rating, Steam Deck status, HowLongToBeat, Achievements, PEGI (Age Ratings), and more
Import all your non-Steam games: Epic, GOG, Amazon, Lutris, Bottles, itch.io, Flatpak, even ROMs with 16 emulator definitions
Metadata that survives Steam updates - we overlay your edits on top of Steam’s data so they don’t get wiped
Built-in auto-updates for AppImage users - downloads in background, atomic replace with rollback if something goes wrong.
Steam Deck: Responsive UI that adapts to 1280x800. AppImage works in Desktop Mode, survives SteamOS updates. No pacman hacks needed.
Tested on both of my SteamDecks - LCD (512GB) and OLED (1TB). On the LCD one it was a bit tricky because I installed CachyOS Handheld Edition on it and installed the AUR, Oled is original SteamOS where I used the AppImage!
It’s my first App, please be patient with me 🙃 I just want to give something back instead of using it just for my own.
TBH: AI tools helped during development - mostly for boilerplate, tests, docs and docstrings because I really hate writing documentation 🙄).
Architecture decisions, feature design, and all the tricky stuff (VDF binary parser, Smart Collections engine, Steam OAuth2) were done by me. Every line was reviewed and tested manually.
I’m not gonna pretend AI doesn’t exist in 2026, but this isn’t a ChatGPT copy-paste job.
It’s a vision I brought to life to help myself, and that I want to share now with the best OS community out there. No matter what Distro!
Linux is awesome, sadly it took me 30 years to realize that, using Windows only!

That is correct. We should strive for the best but this also means choosing the battles one wants to fight and the battle of “looking into everything if it has ai-generated code in it” is not the one I am willing to exhaust my time and strength with.
