Your games, your friends,
one launcher.
Apeiron installs and updates APERTURESyndicate games and apps, gathers what you already play from Steam, Epic and GOG, and keeps your friends one keypress away — even in the middle of a game.

One window, and it is on your machine.
Pick a folder, see how much space it needs, choose your shortcuts. Games land in Start and in Windows Settings › Apps like any other program — no administrator prompt, no second installer.

Close the lid mid-download. Apeiron picks up from the last finished piece, not from zero.
Releases are cut into content-addressed pieces, so an update brings only what actually changed.
Every release is signed. A file that does not match its signature is never written to your disk.
“Check files” compares the install against the release and downloads only the broken parts.
An invite you can answer in one click.
A quiet card in the corner when a friend comes online or starts a game. When they call you into their party, Join drops you straight into it — Apeiron starts the game and the game joins the party by itself.
Shift+Tab, without leaving the game.
The overlay sits on top of the game window: friends and invites, your session time and game stats, and clips — Apeiron keeps the last moments in memory with your graphics card and saves them with sound when you press Alt+F12. Nothing is injected into the game.

Stats, achievements and add-ons in one place.
Each game has its own page: what it is, your time in it, achievements and stats from your account, and the DLC and mods that belong to it. Your library also picks up what you already play elsewhere.

Apeiron replaces it. Your library moves over on install — apps you set up there are picked up from disk without downloading them again, and ASInstaller removes itself.
Start with one exe.
Download it, run it, and it installs itself as a proper app. Signed by APERTURESyndicate OÜ.
