Building a quick prototype or trying out a new tool shouldn’t require navigating billing setups or worrying about surprise charges. That’s why we’re thrilled to announce the no-cost trial for Firebase Data Connect.

Starting today, you can spin up a PostgreSQL database instance for no cost for 90 days—no credit card required. Just initialize your project and start prototyping. Here’s how it works:

No-cost trial on Spark plans

If your project is on the free Spark plan—meaning you don’t have a billing account linked—it’s eligible for a limited-time trial at no cost. You can now provision a PostgreSQL database instance through Data Connect in the console:

• No credit card required: No billing plan is required for the Spark plan.
• 90-day lifespan: You can create one trial database instance over the lifetime of a single Firebase project. The database instance will be suspended after 90 days.
• Hardware: The trial provisions a PostgreSQL 17 instance equivalent to a db-f1-micro, giving you 1 vCPU, 10 GB of SSD storage, and around 628 MB of memory.
• Daily quotas: The instance handles a daily limit of around 8000 operations and 330 MiB of egress.
• Management: Use the gcloud sql family of CLI commands to interact with the instance directly.
• Configuration locks: You cannot change core settings like storage and memory limits. Cost-incurring operations—like creating read replicas, enabling High Availability, or initiating manual backups—are blocked.

What happens after 90 days?

We’ll send you an alert before your trial expires. At the 90-day mark, your database will be suspended and enter a 30-day grace period. If you’re ready to take your app to production, simply upgrade your project to the Blaze (pay-as-you-go) plan (see pricing here) to unsuspend your instance and unlock configuration controls. If you choose not to upgrade, the instance will be safely deleted after the grace period.

No-cost trial on Blaze plans

If your project is on the Blaze plan and has a billing account attached, you qualify for a no-cost Cloud SQL trial for 3 months.

• Project instances: You can have 1 free trial Cloud SQL for PostgreSQL instance per project, which can co-exist with any number of paid instances.
• Trial quotas: You have a total of 5 free trials available per billing account.
• Hardware: Equivalent to a PostgreSQL 17 db-f1-micro instance that has 1 vCPU, 10 GB SSD storage, and around 628 MB of memory.
• Configuration Limits: Unlike the Spark plan trial, Blaze users can change configuration settings—like adding compute resources, setting up a private IP, or creating read replicas. However, if you make any changes to your database instance configuration, you will exit the trial and be billed according to Cloud SQL pricing.
• After 3 months: Once the 3-month trial period ends, you are automatically charged according to standard Cloud SQL pricing.
