About great-on-deck-search

great-on-deck-search is a free, open-source browser extension available for Chrome, Firefox, and other Chromium-based browsers. It is designed to address a gap in the Steam desktop store, which does not natively display Steam Deck verification status for games.

The extension pulls verification data directly from Steam and ProtonDB medal information, displaying both prominently on Steam Store app pages, search results, wishlists, profile game lists, and the store front page. As of version 1.2.0, it is compatible with the SteamDB extension and also surfaces Steam Deck HQ review ratings, breakdowns, and author information on app pages. It uses session-based caching to reduce repeated load times, and includes a settings menu to toggle specific features, with a page reload required for changes to take effect.

It is suited for Steam Deck owners and PC gamers who want to quickly check a game’s compatibility with the Steam Deck before purchasing or adding it to their library.
