It can be used for real-time collaboration, syncing data across clients, and building smart clients. Omander demonstrated some sample apps built with Firebase, including a collaborative Tetris game. Firebase also supports features like authentication, security rules, transactions, queries, hosting, and offline support. Omander emphasized that Firebase allows building applications without having to manage servers yourself.
