One shelf for every game you own.

Parallax Launcher finds the games already on your disk, fills in their artwork, and starts them. Everything it knows stays on your computer — no account, no telemetry, and a library you can open in a text editor.

Free software under the GNU GPL v3. No install — make it executable and run it.

The Parallax Launcher library: a grid of game cover art over a dark starfield.
What it does

It reads what Steam already knows.

No scanning folders and hoping. Parallax opens Steam's own installation records, so what it shows you is what is actually on the disk.

Finding

Your installed games, exactly

Reads Steam's library folders and install manifests directly — across every drive, with the real name and app id for each one.

Launching

Through Steam, or straight past it

Hand the game to Steam, or run it directly so the Steam window never jumps to the front. Set per game, and it shows the exact command first.

Artwork

Covers, without a key

Pulls official covers and banners from Steam's public images — free, no sign-up, no rate limit. Add a SteamGridDB key and the community's work opens up too.

Playtime

Hours you already earned

Counts the sessions it starts, and merges in what Steam recorded before you ever opened this — taking the larger number, never overwriting.

Compatibility

Proton, Wine, and the rest

Per-game runtime, launch options with Steam's %command% syntax, environment variables, GameMode and MangoHud.

Yours

On your machine, in plain text

The library is a text file. The images are ordinary images. Nothing is uploaded anywhere, and there is no account to make.

Download

Two files. Take the first one.

Both are built from the same source by the same automated run.

.AppImage Updates itself
Any distribution

One file. Make it executable and run it — nothing is installed and nothing is left behind. Because it is a single file, the app can replace it: it watches for new releases and offers to fetch one.

Download AppImage
.deb
Debian · Ubuntu · Mint

Installs the way your other software does, and belongs to your package manager afterwards — so updates come from there rather than from the app itself.

Download .deb

Prefer to run it from source? npm install && npm start in App_Core/. Windows builds exist in the repository but are not published yet.

Up close

Everything it will do, before it does it.

Compatibility settings the way Steam lays them out — and one line the others leave out: the exact command that is about to run.

Languages

Eight, all the way through.

Every string in the app exists in all of them — not a partial translation that falls back to English halfway down a screen.
