The Depressurizer alternative for Linux. Organize your Steam library, auto-categorize games, edit metadata, and take control of your collection - with features Steam doesn't have.

Steam has dynamic collections - but they've been AND-only since launch, with a handful of basic filters. Want games that are either "Platinum on ProtonDB" or "Native Linux"? Impossible in Steam. You can only narrow down, never combine alternatives.

Our Smart Collections are a full-blown rule engine with capabilities Steam will never match:

• AND / OR / NOT operators with nested rule groups - build complex logic like (Genre = RPG AND ProtonDB = Platinum) OR (Genre = Strategy AND Deck = Verified). Groups let you combine conditions however you want - no limits, no workarounds
• 21 filter fields across every dimension of your library: playtime, review scores, Steam Deck status, ProtonDB ratings, achievement completion, HowLongToBeat times, tags, genres, release year, developer, publisher, platforms, languages, app type, and more
• 12 operators including range queries - filter games between 10-50 hours playtime, or review scores above 90%, or tags matching a regex pattern
• Language-independent tag matching - switch your Steam tags from English to German (or any language), and your rules keep working. We match by Steam's internal Tag IDs, not by localized names
• 12 ready-made templates to get started: "Unplayed gems", "100h+ club", "Deck verified", "Quick play (<5h)", "Almost done (75%+ achievements)", and more
• Live preview - see matching games update in real-time as you build your rules
• Import & Export as JSON - share your setups with friends or back them up

The clever part: In the Steam client, our Smart Collections appear as regular static collections - Steam doesn't even know the difference. But in SLM, they're fully dynamic and infinitely more powerful than anything Steam offers.

Example: "Show me all RPGs rated 'Platinum' on ProtonDB with more than 20 hours playtime that I haven't 100%'d yet - OR any Strategy game verified for Steam Deck - but exclude anything tagged 'Visual Novel'." One collection. Two rule groups. Automatic. Always up to date. Impossible in Steam.

If SLM saves you time organizing your library, consider supporting its development. Every contribution - no matter how small - helps keep this project alive and growing.

Thank you to everyone who has already contributed - you're amazing! 🙏

Automatically organize your entire library into meaningful collections with 17 different AutoCat rule types:

Tags | Genres | Publishers | Developers | Franchises | Flags | User Score | HowLongToBeat | Year | VR Support | Language | Curator | Platform | Hours Played | Deck Status | Achievements | PEGI Rating

Each rule type has its own configuration - set thresholds, define ignore lists, choose prefix/suffix patterns, and combine multiple rules into powerful categorization profiles. Smart ignore lists filter out generic tags like "Singleplayer" so your categories stay meaningful.

Got 500+ games? Hit "Auto-Categorize" and watch them sort themselves into clean, logical collections in seconds.

Edit game names, sort titles, developers, publishers, and release dates - all stored locally. What makes this special:

• Overlay System: Your modifications are stored separately from Steam's data in custom_metadata.json. When Steam overwrites appinfo.vdf (which it does on login when the server change-number bumps), your edits are automatically re-applied on the next SLM start - and live, while SLM is running, via a file watcher. Like Git rebasing for metadata: Steam provides "upstream", your edits are "patches".
• Bulk Edit: Select hundreds of games, change a field, apply. Done.
• Custom Sort Titles: Make "The Witcher 3" sort under "W", not "T". Edits land in the path Steam actually reads (appinfo.common), with internally-consistent SHA-1 hashes so Steam accepts the file instead of wiping the cache.

No other Steam library tool does this. Depressurizer loses your changes when Steam updates. We don't.

Browse and download covers, heroes, logos, and icons from SteamGridDB - the largest community-driven game artwork database.

• Visual browser with thumbnail previews - see what you're picking before you apply it
• Filter by type: static, animated (GIF/APNG/WebM), NSFW, humor, epilepsy warning
• Badge system with animated slide-down indicators - colored stripes show content tags at a glance
• One click to apply - artwork is downloaded and set as your game's cover instantly

Batch-enrich your entire library with data from multiple sources - all cached locally in SQLite for instant access:

Hit "Enrich All" and grab a coffee. When you come back, every game in your library has full metadata.

• QR code login or password login via Steam's official OAuth2 (IAuthenticationService)
• Tokens stored encrypted (AES-GCM) with machine-derived keys, or in your system keyring
• Automatic token refresh - no re-login on every app start
• The Steam Web API Key is optional thanks to OAuth2 - but adding it is highly recommended for full functionality. You can configure it directly in the app under Settings.

No sketchy browser session tokens. No API keys in plain text config files. Just scan, login, done.

Full English 🇬🇧 and German 🇩🇪 interface with complete i18n - zero hardcoded strings in the entire codebase.

• Separate settings for UI language and tag language - use English UI with German Steam categories, or any combination
• Localized dates - "07. Dez 2024" in German, "07 Dec 2024" in English
• Community translations welcome - download the template files, translate, and submit a PR (details below)

Developed with PyQt6 for seamless desktop integration. This is not a Windows app with a Linux port bolted on - it's built on Linux, for Linux, from day one.

• Steam Deck compatible - works in Desktop Mode
• Wayland & X11 supported
• AppImage, AUR, .deb, .rpm & tar.gz packaging available
• Windows support is planned - but Linux always comes first

Got games scattered across Epic, GOG, Amazon, Lutris, Bottles, itch.io, Flatpak, and emulators? SLM finds them all - and adds them to Steam as Non-Steam shortcuts in one go. Imported shortcuts are also pulled into SLM's main library, so you can drag them into Smart Collections like any Steam game.

Launcher parsers (9): Heroic (Epic/GOG/Amazon/Sideload), Lutris, Bottles, itch.io, Flatpak, plus existing entries from shortcuts.vdf. Heroic Sideload picks up manually added apps in Heroic (e.g. WarCraft 2 remastered, Adobe Photoshop) and launches them via Heroic so your existing Wine prefix and save states are preserved.

Smart Emulator Detection (9 parsers, no hardcoded ROM paths) - SLM reads game directories straight from each emulator's own config file, so it always finds your ROMs wherever you keep them:

EmuDeck is a fallback hint provider for emulators that don't have their own library config. AppImages are auto-discovered in ~/Applications, ~/AppImages and other standard Linux user paths. No more hardcoded /mnt/volume/Emulation/roms style paths - everything comes from the emulator itself or your settings.

Settings tab "Emulators" - per emulator: status badge (Flatpak / System / AppImage / Config-only), custom game directories, executable override, and a per-system default-emulator picker for when multiple emulators support the same system (e.g. choose between Eden/Ryujinx for Switch).

Bidirectional shortcut sync - non-Steam shortcuts from shortcuts.vdf show up in SLM's main library with their tags as categories. Drag them between collections in SLM and the change is written back to both shortcuts.vdf and Steam's cloud-storage, so the collection populates in Steam's sidebar after the next restart.

Duplicate protection - games already in Steam are detected and skipped. Nintendo title updates (e.g. Game [v0].nsp + Game [v327680].nsp) collapse into a single Steam shortcut so you don't end up with broken update-only entries.

Platform collections - imported games are automatically sorted into Steam collections by platform. In SLM's sidebar, each collection gets a visual emoji indicator for instant recognition:

Manual SteamGridDB search - the cover picker now has a free-text search field. Essential for non-Steam shortcuts whose hash-based AppIDs are unknown to SteamGridDB (the search runs automatically when the picker opens for a shortcut).

External Games dialog QoL - resizable columns, deselect-all / select-all toggle so you don't have to uncheck 200 games one by one when you only want 2.

Binary VDF parser - reads and writes Steam's shortcuts.vdf format with byte-for-byte accuracy. Batch import - scan all platforms at once, pick what you want, add them all with progress tracking.

Steam's own "Add a Non-Steam Game" dialog can select multiple apps - but it only sees what's in your PATH, not your actual game libraries. SLM scans Heroic, Lutris, Bottles, every installed emulator and your existing shortcuts directly, knows exactly what's installed, and organizes everything into clean collections automatically.

AppImage users get seamless in-app updates - no manual downloads, no terminal commands. SLM checks GitHub Releases automatically (configurable: daily, weekly, monthly, or never), shows full release notes with changelog, downloads in the background with progress tracking, and restarts into the new version with one click. If anything goes wrong, the previous version is automatically restored.

• Atomic replace with rollback - update can't leave you with a broken install
• "Skip Version" button - dismiss updates you don't want without being nagged
• Configurable - set your preferred check interval in Settings, or check manually anytime

AUR and Flatpak users update through their package manager as usual.
