Realtime Database

Realtime Database is Firebase's original database. Firebase recommends Cloud Firestore instead of Realtime Database for most developers starting a new project. However, there are certain use cases when Realtime DB is appropriate.


Stored: The total amount of storage Realtime DB uses. The first GB is free (about 20 million chat messages), and $5/GB thereafter.

Downloaded: How much data you’ve downloaded from Realtime DB over the course of the month. The first 10 GB each month is free (about 200 millions chat messages), and $1/GB thereafter.


Firestore is a cloud-hosted, NoSQL database with live synchronization and offline support. It is great for serverless apps.


Doc Reads: The first 50k each day are free, then $0.06 for every 100k thereafter.

Doc Writes: The first 20k each day are free, then $0.18 for every 100k thereafter.

Doc Deletes:The first 20k each day are free, then $0.02 for every 100k thereafter.


Modern web hosting that includes a global CDN and a free SSL certificate for a great low-latency experience.


Stored: The first 1GB is free, then $0.026/GB thereafter.

Transferred: The first 10GB per month is free, then $0.15/GB thereafter.

Cloud Functions

Allows for custom backend code without needing to manage and scale your own servers. Functions can be triggered by events from other Google products or webhooks.


Invocations: The first 125k each month is free, then $0.40/million thereafter.

CPU Seconds: The amount of CPU cycles a month your functions use. The first 40k CPU seconds are free, then $0.01 per 1/k after.

Outbound Networking: Traffic to other Google services is free, otherwise $0.12/GB.

The estimated cost on the Firebase console Functions does not include the free tier discount. The discount will be applied at the month end on your Google Bill -> Cost Table.

Cloud Storage

Store and share content including images, audio, and video in a secure environment.


Stored: The first 5GB is free, and $0.026/GB thereafter.

Downloaded: The first 1GB per day is free, and $0.12/GB thereafter.

Upload: The first 20k operations each day is free, and $0.05/10k thereafter.

Download: The first 50k operations each day is free, and $0.004/10k thereafter.
