GOG Galaxy vs PlayNANOO SDK

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.

PlayNANOO SDK is a backend service for game and app developers who want online functions without building a server. Its feature list covers accounts, forums, help desk, receipt validation, inboxes, cloud data, cache, leaderboards, invitations, friends, cloud code, virtual currency, coupons, chat, guilds, remote configuration, push notifications, and game and event logs. Accounts can connect with email, Facebook, Google, and Apple IDs. Documentation includes Unity plugin and REST API guides. Cloud Code runs scripts on the server for services intended to be more secure. API usage is measured by request size: an 8KB request is one call, while 24KB counts as three. The Dev / Free plan costs nothing and includes free API calls and 1GB monthly disk capacity. Basic costs $19.99 a month for 500,000 calls and two accounts; higher plans increase limits. Extra storage costs $1 per additional 1GB, with no database usage fee.
