Valve’s new Steam Machine put the living-room PC back on the table, and a recent XDA-Developers piece argued it competes with the Mac mini more than any console. The point stuck with us. Most people already own a box that could do the job, whether that’s an Intel NUC gathering dust, an old small form-factor tower, or a modern mini PC bought for work. The gap between a desk PC and a Steam Machine is almost entirely software.
We spent a couple of weeks running the same eight apps on a Beelink mini PC and a slightly older Ryzen box hooked into a 4K TV. This is our shortlist of the best apps for HTPC gaming, with what each one is actually good at and where it stumbles once you sit ten feet away with a controller in hand.
What to look for in an HTPC gaming app
The desk-to-couch jump breaks a lot of software that works fine on a monitor. When we tested each app, we watched for a few things.
- Controller-first navigation. Every menu should be reachable with a gamepad, without a mouse fallback.
- Big-screen typography. Fonts and hit targets that read from a sofa, not from a swivel chair.
- Boot-into-game behavior. The HTPC should land in the game launcher, not the Windows desktop.
- Cross-store library. Steam is the anchor, but Epic, GOG, Xbox, and emulator ROMs should sit in the same list.
- Streaming to a couch screen. Optional, but useful if the gaming rig lives in another room.
- Emulator front-end support. Retro libraries need scraped artwork and a shell that hides file paths.
The shortlist at a glance
| App | Best for | Platforms | Free? | Standout |
|---|---|---|---|---|
| Steam Big Picture | Steam-only living rooms | Windows, Linux | Yes | Ships with Steam, controller-native |
| Playnite | Cross-store Windows library | Windows | Yes | Aggregates every PC storefront |
| Bazzite | SteamOS on any mini PC | Linux | Yes | Immutable Fedora spin with Steam preinstalled |
| Sunshine + Moonlight | Streaming to the TV | Windows, Linux, clients everywhere | Yes | Self-hosted GeForce Now, basically |
| Kodi with Retroplayer | Media center plus retro games | Windows, Linux | Yes | One remote for movies and emulators |
| ES-DE (EmulationStation) | Retro front-end | Windows, Linux, macOS | Yes | Clean shell over RetroArch |
| GameHub | Cross-store Linux library | Linux | Yes | Steam, GOG, Humble in one grid |
| Lutris | Wine and Proton runner manager | Linux | Yes | Installs non-Steam Windows games on Linux |
1. Steam Big Picture
Steam Big Picture is the obvious starting point and, for a lot of people, the finish line too. Valve’s controller-first shell now doubles as the SteamOS interface, so it already knows how to handle a gamepad, per-game input maps, and TV-safe overlays. If your HTPC exists to play Steam games on a couch, this covers most of the work by itself.
- Where it falls short: It only surfaces Steam games. Epic, GOG, Xbox, and emulators need a separate launcher, and non-Steam shortcuts still feel like a workaround.
- Pricing: Free.
- Platforms: Windows, Linux (bundled with Steam).
- Download: Steam
- Bottom line: The default answer, especially if most of your library already lives on Steam.
2. Playnite
Playnite is the Windows answer to the cross-store problem. It pulls games from Steam, Epic, GOG, Xbox, Amazon, EA, Ubisoft, and Battle.net into one grid, scrapes cover art automatically, and launches each title through its native client. The Fullscreen mode is a proper couch UI with big tiles and gamepad navigation.
- Where it falls short: Windows only. First-time setup asks you to sign into every storefront, which takes a while.
- Pricing: Free, open source.
- Platforms: Windows.
- Download: Playnite
- Bottom line: The best cross-store launcher on Windows, and a strong reason to keep Windows on your HTPC.
3. Bazzite
Bazzite is what happens when SteamOS ideas meet a general-purpose desktop. It’s an immutable Fedora Atomic spin that boots straight into Steam’s Gaming Mode, with drivers, codecs, and controller support already configured. On a mini PC with a decent iGPU or a small discrete card, it turns the box into something that behaves like a Steam Deck.
- Where it falls short: Anti-cheat titles that block Linux still won’t run, immutable roots take some getting used to, and NVIDIA setups need the NVIDIA image variant.
- Pricing: Free, open source.
- Platforms: Linux.
- Download: Bazzite
- Bottom line: The fastest way to a Steam Machine feel on hardware Valve doesn’t sell.
4. Sunshine + Moonlight
Sunshine + Moonlight is a self-hosted alternative to GeForce Now. Sunshine runs on the machine with the GPU, Moonlight runs on the client, and together they stream games at low latency to whatever screen you want. If your HTPC is modest and your real gaming PC lives in an office, this pair puts the office rig on the TV without moving hardware.
- Where it falls short: Wants a wired network or strong Wi-Fi 6, and the setup involves certificates and firewall rules the first time.
- Pricing: Free, open source.
- Platforms: Sunshine on Windows and Linux, Moonlight clients on almost everything.
- Download: Sunshine and Moonlight
- Bottom line: The right pick when the HTPC is a thin client and the heavy GPU lives elsewhere.
5. Kodi with Retroplayer
Kodi with Retroplayer turns a media center into a retro console. Kodi already handles movies, music, and live TV with a remote-friendly interface, and Retroplayer adds emulator cores that treat ROMs as another library alongside films. For families who want one box for everything, this is the shortest path.
- Where it falls short: Retroplayer’s core support lags behind RetroArch, and setup for scraped artwork takes some manual work.
- Pricing: Free, open source.
- Platforms: Windows, Linux.
- Download: Kodi
- Bottom line: Best if the HTPC has to be a media center first and a game system second.
6. ES-DE (EmulationStation)
ES-DE (EmulationStation) is a dedicated front-end for RetroArch and standalone emulators. It handles scraping, per-system themes, and controller navigation with none of the ROM management weirdness that trips people up in RetroArch on its own. On a TV, it looks and behaves like a purpose-built retro console.
- Where it falls short: It doesn’t emulate anything itself, so you still install RetroArch or standalone cores underneath. First-time scraping needs a keyboard.
- Pricing: Free.
- Platforms: Windows, Linux, macOS.
- Download: ES-DE
- Bottom line: The retro layer we would put on any HTPC that plays classics regularly.
7. GameHub
GameHub does for Linux what Playnite does for Windows. It pulls games from Steam, GOG, Humble, and Itch into one grid, handles emulator entries, and can even manage Wine prefixes for non-native titles. The interface is tidy, and it plays well with a controller once you tweak a couple of settings.
- Where it falls short: Development has slowed, and some newer storefront APIs need manual token entry. Big Picture-style navigation is functional but not as polished as Playnite.
- Pricing: Free, open source.
- Platforms: Linux.
- Download: GameHub on Flathub
- Bottom line: The right cross-store launcher for a Linux HTPC that isn’t running Bazzite’s Gaming Mode.
8. Lutris
Lutris is the tool that makes a Linux HTPC useful for games that were never meant to run on Linux. It’s a manager for Wine, Proton, and dozens of other runners, with community install scripts for popular titles from GOG, Epic, and Battle.net. Point it at an installer, and it handles the compatibility layer for you.
- Where it falls short: Install scripts occasionally break when publishers change their installers. Its own UI is fine on a desk, less friendly on a couch.
- Pricing: Free, open source.
- Platforms: Linux.
- Download: Lutris
- Bottom line: Pair it with GameHub or Bazzite so the launch UI stays TV-friendly while Lutris does the heavy lifting.
How to pick the right one
Match the app to how you actually plan to use the box.
If the library is almost entirely Steam and the HTPC is dedicated to gaming, Steam Big Picture on Windows or Bazzite on Linux is enough on its own. Bazzite gets you closer to a real Steam Machine because it boots straight into Gaming Mode and hides the desktop.
If you buy games from Epic, GOG, and Xbox as well, use Playnite on Windows or GameHub on Linux as the shell, and let Steam sit inside them as one storefront among several. Add Lutris on Linux when a specific non-Steam Windows title refuses to cooperate.
If retro games are the main event, put ES-DE on top of RetroArch, or use Kodi with Retroplayer when the same box also has to handle movies and music.
If the HTPC is a low-power thin client and the real GPU lives in another room, skip the launcher question and set up Sunshine + Moonlight. The couch box becomes a display, and the office box does the work.
FAQ
What is the best Steam Big Picture alternative? Playnite on Windows and GameHub on Linux are the closest replacements, and both add cross-store libraries that Big Picture doesn’t. For a full SteamOS-style shell on non-Valve hardware, Bazzite is the better choice.
Is Playnite free? Yes. Playnite is free and open source, and it doesn’t take a cut of purchases or add ads. Extensions and themes from the community are free as well.
Can I turn my mini PC into a Steam Machine? Yes. Install Bazzite for the closest SteamOS experience, or run Steam Big Picture on Windows and set it to launch at boot. Either approach gives you a controller-first shell on a mini PC.
What is the best HTPC OS? For gaming-first HTPCs, Bazzite Linux gets you a SteamOS-like experience with driver setup handled for you. For libraries that include a lot of non-Steam Windows-only titles, Windows 11 with Playnite is still the safer pick because of broader anti-cheat compatibility.
Do I need Linux for a Steam Machine build? No. Windows with Steam Big Picture works, and so does Bazzite. Linux gets you closer to how SteamOS behaves and boots faster into a controller UI, but the choice comes down to which titles you play and whether they support Proton.
Can I run emulators alongside Steam on the same HTPC? Yes. Playnite, GameHub, and ES-DE all treat emulator libraries as first-class entries, and you can launch RetroArch cores directly from those shells without leaving the couch UI.
