Firebase pricing plans

This page describes the Firebase pricing plans, including how billing works for Firebase and how it connects with other Google services.

Firebase offers two different pricing plans, the Spark plan and the Blaze plan. Here's a brief overview of each plan, but for detailed information, visit the sections below on this page.

Spark pricing plan

No payment information needed to get started
or to only use free Firebase products

Blaze pricing plan

Attach a billing account to access more services
and usage levels beyond the free-usage quota

Full usage of free Firebase products and features Full usage of free Firebase products and features
Free-usage quota* for paid Firebase products Free-usage quota* for paid Firebase products
Pay-as-you-go pricing for any additional usage of paid Firebase products
Access to Cloud Functions
(free-usage quota, then pay-as-you-go pricing for additional usage)
Access to paid Google Cloud products and features
* Depending on the product, the amount of free-usage quota available for the Spark vs Blaze plan may be different. Read more in this FAQ.

For a detailed product-by-product breakdown for each pricing plan, check out the Firebase pricing page. On that page, you can learn about the free Firebase products, free-usage quotas, and pay-as-you-go pricing for Firebase products.

Also, most Firebase products provide product-specific documentation about usage, quotas, and pricing. They often provide usage-to-billing examples for the product. Visit a product's section in the Firebase documentation to find this type of information.

The following illustration shows how pricing plans (and billing accounts) are associated with projects and apps.

Relationship between pricing plans and projects and apps



Spark pricing plan

When you're in the initial stages of developing your app, start out with the Spark pricing plan. You don't need to provide any payment information to get started using most Firebase features right away!

And if you're only using free Firebase products, like FCM and Crashlytics, you can use the Spark plan in production apps.

What's included with the Spark plan?

The Spark plan includes the following access to services:

  • Full usage of the free Firebase products and features (like social sign-in methods, FCM, and Crashlytics)
  • Free-usage quotas for paid Firebase products (like Cloud Firestore, Cloud Storage, and Hosting)

Example scenarios

Here are some examples of usage and billing on the Spark plan:

  • Your app uses Remote Config, Cloud Messaging, and Crashlytics. You get access to all of the features in these three products — for free — even if your app has several million users.

  • Your app uses custom Authentication, Crashlytics, and Cloud Firestore. You get access to all the features for custom Authentication and Crashlytics (no matter how many users you have), plus you get 20,000 Cloud Firestore document writes and 50,000 document reads every day — for free.

Important facts to remember about the Spark plan

Note the following about the Spark pricing plan:

  • If you exceed the free quota limit in a calendar month for any product, your project's usage of that specific product will be shut off for the remainder of that month.

    • This applies to all apps registered with that Firebase project.

    • To use that specific product again, you'll need to wait until the next billing cycle or upgrade to the Blaze pricing plan.

  • Paid Google Cloud products and features (like Pub/Sub, Cloud Run, or BigQuery streaming for Analytics) are not available for projects on the Spark plan.



Blaze pricing plan

If your project requires the capabilities provided by the paid services, switch to the Blaze pricing plan. A Firebase project on the Blaze plan has a Cloud Billing account attached to it, which enables your project and apps to access more services and higher usage levels.

What's included with the Blaze plan?

The Blaze plan includes the following access to services:

  • Full usage of the free Firebase products and features (like social sign-in methods, FCM, and Crashlytics)

  • Free-usage quotas for paid Firebase products (like Cloud Firestore, Cloud Storage, and Hosting)

  • Pay-as-you-go pricing for any additional usage of paid Firebase products

  • Free-usage quota for Cloud Functions for Firebase, then pay-as-you-go pricing

  • Access to paid Google Cloud products and features (like Pub/Sub, Cloud Run, or BigQuery streaming for Analytics)

If your project stays within the Blaze plan's free-usage quotas for paid products, then you won't see any billing for those products (with the exception of Cloud Functions). But if you do happen to exceed the free-usage quota, you only pay for the resources that you consume — this is why the Blaze plan is often called the "pay-as-you-go" plan.

Example scenarios

Here are some examples of usage and billing on the Blaze plan:

  • Your app uses Remote Config, Cloud Messaging, and Crashlytics. You get access to all of the features in these three products — for free — even if your app has several million users.

  • Your app uses custom Authentication, Crashlytics, and Cloud Firestore. You get access to all the features for custom Authentication and Crashlytics (no matter how many users you have), plus you get 50,000 Cloud Firestore document reads and 20,000 document writes every day — for free.

    But if your project's usage of Cloud Firestore is higher than those daily quotas, you're charged for the reads/writes that day which exceed the 50K or 20K count.

Important facts to remember about the Blaze plan

Note the following about the Blaze pricing plan:

  • Depending on the product, the amount of free-usage quota available for the Spark vs Blaze plan may be different. Read more in this FAQ.

  • Most Firebase products and features have quotas and pricing based on a daily usage, but some are based on monthly or hourly usage. Cloud Functions, for example, has a free-usage tier that resets every month, but Cloud Firestore and Cloud Storage have free tiers that reset every day. Read more in this FAQ.

Google Cloud Billing accounts

When your project is on the Blaze pricing plan, your project is associated with a Google Cloud Billing account. Here are some quick facts about Cloud Billing accounts:

  • Cloud Billing accounts require a payment method. This includes most major credit cards, as well as bank accounts and PayPal payment methods (if supported in your country). For more detailed information, refer to the Cloud Billing documentation.

  • You can associate multiple Firebase projects with a single Cloud Billing account. All these projects will be on the Blaze pricing plan.

If you're new to Firebase and Google Cloud, check if you're eligible for a $300 credit and a Free Trial Cloud Billing account to try out our services.



Switching between pricing plans

Upgrading from Spark to Blaze

You can upgrade to the Blaze pricing plan in the Firebase console.

For all intents and purposes, upgrading to the Blaze pricing plan means that you're adding a Cloud Billing account to the associated Google Cloud project.

The following actions and situations will automatically upgrade your pricing plan from Spark to Blaze:

  • Adding a Cloud Billing account to your project via the Google Cloud Console

  • Using Google Cloud services (like Pub/Sub or Cloud Run) or Google Maps APIs in the same project

    For example, if you start using a Google Cloud service via the Google Cloud Console, you'll be required to add a Cloud Billing account — this automatically upgrades your Firebase pricing plan to the Blaze plan.

If your project upgrades from Spark to Blaze, be aware of what will happen:

  • Depending on the product, the amount of free-usage quota available for the Spark vs Blaze plan may be different. Read more in this FAQ.

Downgrading from Blaze to Spark plan

You can downgrade to the Spark pricing plan in the Firebase console.

The following actions and situations will automatically downgrade your pricing plan from Blaze to Spark:

  • Removing the associated Cloud Billing account from your project via the Google Cloud Console

  • Closing the Cloud Billing account associated with your project
    Note that Cloud Billing can close accounts based on the payment status or history. Learn how to resolve Cloud Billing issues.

If your project downgrades from Blaze to Spark, be aware of what will happen:

  • Your project loses access to any paid Google Cloud services, like Pub/Sub, Cloud Run, or BigQuery streaming for Analytics.

  • Your project loses access to any non-default Realtime Database instances or non-default Cloud Storage buckets.

    • The data in these instances and buckets doesn't get deleted, but you won't have access to the data (no read/write access from your app, no console access, and no REST API access).

    • To re-enable access, upgrade to the Blaze pricing plan.

    • If you need to delete the data from these non-default instances and/or buckets, but stay on the Spark plan, contact Support.

  • You cannot do new deploys of any new or any existing Cloud Functions.

  • Depending on the product, the amount of free-usage quota available for the Spark vs Blaze plan may be different. Read more in this FAQ.
