Firebase
Firebase is Google's backend-as-a-service platform, offering a NoSQL database (Firestore and Realtime Database), authentication, static hosting, serverless functions and analytics for mobile and web apps. It started as a real-time sync startup called Envolve in 2011, was relaunched as Firebase in 2012, and Google acquired it in October 2014. Firebase runs on a free Spark plan and a pay-as-you-go Blaze plan billed through Google Cloud.

A good fit for
- Mobile apps that need authentication, push notifications and a real-time database quickly
- Small teams that want a managed backend without running their own servers
- Apps that will grow into the wider Google Cloud ecosystem
- Prototypes and MVPs on the free Spark plan before committing to Blaze
Not a good fit for
- Apps that need a relational (SQL) database as the primary data store
- Teams that want an open source or self-hostable backend
- Workloads with unpredictable Cloud Functions or Firestore usage where Blaze costs are hard to forecast
Firebase pricing
The Spark plan is free with fixed no-cost usage limits and no payment method needed. The Blaze plan keeps those free limits but bills for usage beyond them at Google Cloud rates, and includes $300 in free credit for new eligible users.
| Plan | Price | What you get |
|---|---|---|
| Spark (free) | $0 | 1 GiB Firestore storage, 50,000 daily reads and 20,000 daily writes, 10 GB hosting storage, 360 MB a day transfer, auth for up to 50,000 monthly active users. No Cloud Functions or Cloud Storage. |
| Blaze (pay as you go) | Usage-based, e.g. Cloud Functions $0.40 per million invocations beyond 2M free | All Spark limits included free, then billed per use for Firestore, Hosting, Functions, Storage and other services. |

About Firebase
Firebase evolved out of Envolve, a real-time chat API startup founded by James Tamplin and Andrew Lee in 2011. After noticing developers using the chat API to sync app data rather than chat messages, the founders split off the real-time database as its own company, Firebase, which launched publicly in April 2012. Google acquired Firebase in October 2014.
The platform now bundles Firestore (a document database), the older Realtime Database, Firebase Authentication, Cloud Storage, Cloud Functions, Firebase Hosting, Remote Config, Crashlytics and Google Analytics, all managed from one console and billed together.
Firebase is commonly used to build mobile and web apps quickly without managing servers, particularly for authentication, real-time data sync and push notifications, with the option to scale into other Google Cloud services as an app grows.
