GOG Galaxy vs itch app

GOG Galaxy brings game libraries and friends from different gaming platforms into one app for Windows and macOS. It can collect PC and console games, including titles that are not installed, and track achievements, play time, and owned games across connected services. For PC games, it can install and launch titles owned on different platforms. Library tools include filtering, sorting, tagging, changing game visuals, saving views, and editing metadata. Galaxy combines friends lists, online status, activity, and cross-platform chat. Games can enter the library through official or community-made integrations, or be added manually; community integrations are open source, and GOG provides documentation for creating them. Library changes sync between devices, and offline mode is available. GOG says it does not share imported personal data with third parties and removes it from its servers when a platform is disconnected. GOG-specific features include auto-updates, cloud saves, multiplayer, matchmaking, and rollbacks. Other platforms’ client software is needed for their platform-specific features. The app is free with a GOG account.

The itch app is a desktop client for downloading and running games and software from itch.io. Its built-in browser lets users browse creator pages and install titles, while the library keeps downloads together and updates installed games automatically. Users can access collections, bundles, purchases and installed games in the app. Browser-based games can be synced for offline play, and games using itch.io command-line tools can receive delta patches that download only changed data. The client is available for Windows, macOS and Linux, with Windows 7 or newer required, and it is open source and offered in over 20 languages. Creators can provide an app manifest to define launch targets and integrate with the app API. The app registers itch:// and itchio:// links and can create Steam library shortcuts for installed games. Its sandbox limits file access, isolates home directories for Linux games and runs Windows games as less-privileged users. Compatibility problems can still occur, especially on Linux when games do not follow best practices. The listed plan is free.
