「たった半日で認証を実装することができました。以前は、独自のソリューションの作成には何週間もかかり、プロバイダの API に変更が発生するたびにアップデートしなければなりませんでした」- Amine Laadhari, Fabulous CTO
「Firebase Authentication は最低限の設定しか必要としないので、短時間で簡単にソーシャル アカウントへのサインアップが実装できました。コンソールで提供されるユーザー管理機能もすばらしく、簡単に認証システムを実装できました」- Marc Yeongho Kim, Malang Studio CEO 兼 創立者
「ネイティブ広告は今まで以上に直感的なので、アプリの中の目立つ部分に実装しました。ユーザーのクリックスルー率がどう変化したかは、広告のバックエンド情報からリアルタイムで確認できました。そのため、短期間でネイティブ広告の最適化を行い、広告収益を最大化することができたのです」 - Linghit Limited 副社長、Jinnee Lee
