A cross-platform desktop application for organizing and managing your game product keys and activation codes. UniKM features Steam integration, encryption, and a themeable UI. This is a complete rewrite of SteamKM2, using Dart language and Flutter as the front-end.
UniKM keeps all your game keys in one place: organized, searchable, and secure. Whether you have a handful of codes or hundreds from Humble Bundle, Fanatical, Green Man Gaming bundles or from some other place, UniKM gives you a place to store them efficiently. It integrates directly with Steam to enrich your library with cover art, ratings, and tags automatically, and optionally encrypts your database so your keys stay private.
- Add, edit, and delete game entries with title, key, status (used/unused), notes, and tags
- Right-click context menu for quick actions: copy key, mark used/unused, fetch Steam data, delete
- Mark games as used or unused with visual indicators
