Firebase Data Connect pricing

This document explains Firebase Data Connect pricing details.

If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.

Understand Data Connect billing

Firebase Data Connect consists of two billable components:

The Data Connect service itself
The Cloud SQL for PostgreSQL instance that contains your project data.

If you integrate with Vertex AI, you are billed for vector embeddings.

Data Connect service pricing

Network egress has no cost up to 10 Gib/month; more than 10 Gib/month, egress is charged at Google Cloud Internet Data Transfer Rate Premium Tier pricing.
On Blaze plans, operations (queries or mutations) executed from clients incur no cost up to 250,000 operations per month; operations in excess of 250,000 are charged at $4.00 per million.

On Spark plans, you are limited to 8,300 operations per day, after which you won't be able to run any operations.

Note: The price is per operation and is not related to the amount of data read from the database; there is no "per row read" fee. Each Data Connect operation can perform efficient, complex, multi-table queries or multi-row updates.

Cloud SQL instance pricing

Cloud SQL pricing starts as low as $9.37 / month. Pricing varies based on regions and configurations. See Cloud SQL pricing.

No-cost trial on Spark plans

If your Firebase project is on the Spark plan, and you therefore don't have a billing account attached to the project, your project is eligible for a limited-time trial at no cost.

During the trial, you can create one database instance in your project with the following limitations:

The trial lasts 90 days. After 90 days, if you have not upgraded your project to a paid plan (Blaze), the database instance will be archived and won't be accessible to apps. After that, if you haven't upgraded your project 90 days after the database instance is archived, it will be deleted.
The database instance has a daily limit of around 8000 operations and 330 MiB of egress.
The database instance is not viewable or manageable in the Google Cloud console. (If necessary, you can use the gcloud sql family of commands.)
You cannot change database instance settings such as storage and memory limits.
You cannot create additional database instances after the first in Spark projects.

You are allowed a single trial database instance over the lifetime of a Firebase project.

If you upgrade your project to the Blaze plan, your database instance will be migrated to a paid Cloud SQL instance (see above).

No-cost trial on Blaze plans

If your project is on the Blaze plan, and you therefore have a billing account attached to it, you are qualified for a no-cost Cloud SQL trial for 3 months.

To make use of the trial, accept the default configuration when you provision a Cloud SQL for PostgreSQL instance.

5 free trials are available per billing account.
1 free trial Cloud SQL for PostgreSQL instance per project, although you can have multiple paid instances within that project.
The default configuration of your Cloud SQL for PostgreSQL instance is equivalent to a db-f1-micro instance that has 1 vCPU, 10 GB of storage, 628.74 MB of memory.

During the no cost trial, you can add computing resources to your Cloud SQL instance, set up a private IP for your instance, and create a read replica for your instance. When you make any changes to your database instance configuration, you will exit the trial, at which point you will be billed according to Cloud SQL pricing.

After 3 months, you are charged according to standard Cloud SQL pricing.

Vertex AI embedding generation

Using Data Connect with Vertex AI will incur standard usage charges from Vertex AI for embedding generation.

Manage spending

To monitor your Data Connect usage, to access an overall view of all service activity, and links to analyze individual service activity, open the Data Connect product page. Use the dashboards to gauge your usage over different time periods.

To track your Data Connect costs, create a monthly budget in the Cloud console. Budgets won't limit your usage, but you can set alerts to notify you when you're approaching or exceeding your planned costs for the month.

To set a budget, in the Cloud console, go to the Billing section and create a budget for your Cloud Billing account. You can use the default alert settings or modify the alerts to send notifications at different percentages of your monthly budget.
