Steam has been the default PC launcher for two decades, and Valve still hides half its useful settings behind menus most players never open. Bandwidth caps, family sharing exceptions, per-game launch options, and the offline mode that actually works are all buried three clicks deep. The desktop apps below fill the gaps: better library management, richer store data, and features the Steam client refuses to add. Seven picks for Steam power users on Windows, macOS, and Linux.
What to look for in Steam power-user tools
Five things matter more than the shiny screenshots:
- Reads the Steam data folder locally. The best library managers don’t need your Steam credentials; they read the local
appmanifestfiles. - Non-destructive. A tool that changes your Steam library files should back them up. Nothing here should permanently rewrite your Steam config.
- Cross-platform where it can be. Steam runs on all three desktop OSes; not every tool follows.
- Community-audited. Anything that logs into your Steam account or handles your session cookies must be open source or well-known.
- Doesn’t monetise your library. Ignore any tool that pushes coupons or cashback tabs.

The apps
1. Steam — Best client with hidden settings you should turn on
Steam stays the default because most competitors haven’t shipped a store as complete. The features hiding in the client are the ones to enable first: Family Library Sharing at no cost, Big Picture on any desktop, per-game launch options for FPS caps or Proton overrides, and the download bandwidth cap that stops one game from starving the rest of your network. All of it free and already installed if you own the client. The 2026 refresh made the Community tab more useful; most of the good stuff is still one settings pane deeper than it should be.
Where it falls short: UX still shows its age in places. Some settings that should be per-account are per-machine and vice versa.
Pricing:
- Free: The client is free; you pay for games
- Paid: N/A
- Platforms: Windows, macOS, Linux
Download: Steam · Google Play (companion)
Bottom line: Enable Family Sharing, set a download cap, learn the launch options. That’s 80% of the wins.
2. Playnite — Best unified launcher
Playnite is a desktop game library that pulls in every store you use (Steam, GOG, Epic, Xbox, EA, Ubisoft, Origin, Battle.net) and shows them in one grid. Launch buttons still route to the right launcher underneath, but you never need to remember which app you bought a game in. Extensions add metadata scrapers, HowLongToBeat overlays, and completion trackers.
Where it falls short: Windows-only. Native Linux users route through emulators or wait for the port that’s been near-done for a while.
Pricing:
- Free: Everything (open source)
- Paid: N/A
- Platforms: Windows
Download: Playnite
Bottom line: The right home screen if you buy games in more than one store.
3. SteamDB browser extension — Best real store data inline
SteamDB browser extension adds historical price data, real player counts, achievement lists, and the actual internal store metadata directly into every store page you visit. Buying decisions get easier when you can see that the price today is not, in fact, the lowest of the year. Regional prices, price drops, and DLC lists all show inline.
Where it falls short: Browser extension, so it doesn’t touch the desktop client itself.
Pricing:
- Free: Everything
- Paid: N/A
- Platforms: Chromium browsers, Firefox
Download: SteamDB extension
Bottom line: The single extension every buyer should install before their next Steam sale.
4. Depressurizer — Best library organiser
Depressurizer takes a bloated Steam library and files it into categories based on genre, tags, review scores, or your own rules. A 3000-game library goes from a firehose to something you can scroll. Auto-cat rules mean new purchases file themselves. Not touched by Valve in years, but still works and still saves an evening every quarter.
Where it falls short: Windows-only. Interface hasn’t changed since 2014. Requires you to log in once via web browser to pull tag data.
Pricing:
- Free: Everything (open source)
- Paid: N/A
- Platforms: Windows
Download: Depressurizer on GitHub
Bottom line: The best free way to make a big library browseable.
5. Steam ROM Manager — Best for non-Steam games as shortcuts
Steam ROM Manager adds emulated ROMs and non-Steam launchers to Steam as full shortcuts with proper artwork. Big Picture mode then treats a Sega Genesis library exactly like a Steam library. Automatically fetches box art, banners, and hero images from SteamGridDB. Perfect for a Steam Deck or a TV-connected small-form PC.
Where it falls short: Configuring parser sets for the first time takes an afternoon.
Pricing:
- Free: Everything (open source)
- Paid: N/A
- Platforms: Windows, macOS, Linux
Download: Steam ROM Manager
Bottom line: The right tool for a couch-gaming PC with a mixed library.
6. Boxtron — Best for DOS classics through Steam Play
Boxtron wraps DOSBox in the Proton runtime interface, which means every DOS classic on Steam can be launched through Steam Play with the same UX as a Proton title. On Linux especially, this fixes a lot of DOS-era Steam titles that Valve’s default Proton doesn’t handle cleanly. Combine with Roberta for ScummVM.
Where it falls short: Linux-only. Set-once configuration.
Pricing:
- Free: Everything (open source)
- Paid: N/A
- Platforms: Linux
Download: Boxtron on GitHub
Bottom line: The Linux gamer’s fix for DOS titles that misbehave under vanilla Proton.
7. DeckyLoader — Best plugin loader for Steam Deck
DeckyLoader is the plugin manager Valve didn’t ship. Battery overlays, refresh-rate switching, wired-headset audio profile, and CSS themes all install through Decky and update in place. It stays out of the way in Game Mode and only appears when you press the button combo.
Where it falls short: Steam Deck only. A Valve update very occasionally breaks a plugin for a day.
Pricing:
- Free: Everything (open source)
- Paid: N/A
- Platforms: SteamOS
Download: DeckyLoader
Bottom line: The reason Steam Deck feels like an open device.
How to pick the right one
- If you have never touched the Steam settings menu, start there: bandwidth cap, Family Library Sharing, per-game launch options
- If you buy games in Epic, GOG, Xbox, or Ubisoft as well as Steam, install Playnite
- If you shop the Steam sale seriously, install the SteamDB browser extension first
- If your library is over a thousand games, spend an afternoon on Depressurizer
- If you’re building a couch PC or Steam Deck, Steam ROM Manager is the artwork solution
- If you own DOS classics on Steam and run Linux, install Boxtron once and forget it
- If you own a Steam Deck, install DeckyLoader on day one
FAQ
Where are the hidden Steam settings I keep hearing about?
The ones people miss most are: Downloads → Bandwidth cap, In-Game → FPS counter, Family → Family Library Sharing, and Interface → run offline mode. Most of them ship off by default.
Is Playnite better than Steam?
Playnite doesn’t replace Steam; it sits on top and shows every launcher’s library in one place. Launches still route to Steam or Epic or GOG underneath.
Is SteamDB safe to log into?
The extension reads store pages and adds data; it doesn’t log into your account. If you use the SteamDB site itself, you can browse without signing in.
Can I make Steam ignore a game I never want to see?
Yes. Right-click the game in your library, Manage → Hide this game. It disappears from the default list but stays installable.
Does Family Library Sharing cost anything?
No. You can authorise up to 10 devices for up to 5 accounts to share your library, at no additional cost, as long as only one person plays at a time.
