After 12 months of development and testing, we can officially announce that Realtime Database (Firebase) for all platforms is finished and released today! If you have any questions, feel free to ask!

Realtime Database is a plugin for Unreal Engine 4 that lets you integrate Realtime Database functionality of the Firebase system for all platforms.

Firebase is a platform that helps you quickly develop high-quality experiences and grow your user base. You can focus on making your game and not waste time building complex infrastructure. Realtime Database is a cloud-hosted NoSQL database. Data is stored as JSON, synced across connected devices in milliseconds, and available when your game goes offline.
