Firebase

Google · 🔧 BaaS

Firebase is Google's mobile and web application development platform that helps you build, improve, and grow your app.

Overview

Firebase is Google’s app-development platform: a NoSQL realtime store (Cloud Firestore and the original Realtime Database), authentication, cloud functions, hosting, file storage and analytics — all wired together and reachable from client SDKs for web, iOS and Android. It is a fast way to build an app back end without managing servers.

The free Spark plan is generous for prototypes: roughly 1GB Firestore storage, 10GB hosting storage, 125k Cloud Functions invocations and 50k monthly authentications. Beyond Spark you move to the pay-as-you-go Blaze plan.

Firebase fits mobile and web apps that want auth, a synced NoSQL store and serverless functions with minimal setup — particularly when you are already in the Google ecosystem. Confirm the current free-tier limits on the provider’s site.

Pros

✓Tight client SDKs for web, iOS and Android
✓Realtime sync with Firestore and Realtime Database
✓Auth, functions, hosting and storage in one place
✓Generous free Spark plan for prototypes
✓Backed by Google's infrastructure

Cons

✕NoSQL data model can constrain complex queries
✕Pay-as-you-go (Blaze) costs can be hard to predict
✕Vendor lock-in to Google's ecosystem
✕Some Cloud Functions features require the Blaze plan

FAQ

What is the difference between Realtime Database and Firestore?

Both are NoSQL. Firestore is the newer, more scalable document database with richer queries; Realtime Database is the original JSON tree, good for simple low-latency sync.

Is the free plan enough for production?

For small apps it can be. Heavier usage moves you to the pay-as-you-go Blaze plan, so monitor usage to keep costs predictable.

Can I avoid vendor lock-in?

Firebase is proprietary. If portability matters, consider an open alternative such as Supabase.
