Firebase

firebase.google.com

Google's app development platform with auth, Firestore, hosting, and serverless functions.

Overview

Firebase is Google's comprehensive platform for building, deploying, and scaling mobile and web applications. It provides a suite of managed services including databases, authentication, hosting, analytics, and cloud functions—all backed by Google Cloud infrastructure.

The platform is designed to accelerate app development across iOS, Android, Web, Flutter, Unity, and C++. Firebase integrates deeply with Google's AI capabilities, including Gemini, allowing developers to build AI-powered features directly into their applications. It's trusted by major companies like Duolingo, Venmo, and NPR.

Firebase offers a free tier (Spark plan) with generous no-cost usage limits and a pay-as-you-go Blaze plan for scaling. New users can get $300 in free credits to explore all features.
