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.
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.
