One multi-store library
Browse installed games, manually added programs, and owned titles from Steam, XBOX, Epic, and GOG, including games that are not installed.
When Your Library Goes Beyond Steam
Steam Big Picture is excellent when Steam is the center of your setup. Ammonis is for the PC library that also includes XBOX, Epic, Ubisoft, GOG, and more.
The short version
Steam Big Picture is the natural choice for a Steam-centered library. Ammonis is designed for PCs where Steam is only one part of the collection.
Controller-first throughout
Navigate games, launch actions, settings, and system controls from your gamepad.
Per-game settings
Keep each game's display, HDR, audio, RTSS frame limit, and Lossless Scaling choices together.
Keep the parts of Steam you need
See Steam friends' game activity, open their profiles, and browse recently played and most-played games in Ammonis. Open Steam whenever you need its own store, downloads, or other controls.
Different platforms, equally rich game details
Link a game from another platform or a manually added program to its Steam title to bring Steam overview information and news into its details page.
When Ammonis adds the most value
Ammonis is most useful when your games span several stores and you want their launch settings in one place.
Questions, answered.
Can I use Ammonis alongside Steam Big Picture?
Yes. Ammonis runs alongside Steam, so you can switch between the two whenever you like.
Does Ammonis support non-Steam games?
Yes. Ammonis detects installed games from Steam, Epic, XBOX, Ubisoft, GOG, and more.
Does Ammonis replace Steam?
No. Steam still installs, updates, and runs your Steam games. Ammonis gives those games a shared home alongside the rest of your PC library.
Can I add games and tools from outside these stores?
Yes. Add programs from the installed-program list or your own folders. The free version supports up to 20 manual additions; Premium removes that limit. Removed programs stay in a history list where you can restore them within your current limit or permanently delete their library records.
