## Firebase Pricing: The Short Answer

Firebase has two plans. Spark is free, needs no payment method and has fixed usage limits. Blaze is pay as you go: it includes the same no-cost usage as Spark, unlocks more services such as Cloud Functions, and bills you only for usage above the free quotas. Eligible new accounts get $300 of free credit on Blaze. Many Firebase products, including Analytics, Crashlytics for mobile and Cloud Messaging, are free on both plans.

> **Quick answer: How much does Firebase cost?** $0 on Spark. On Blaze there is no monthly fee; you pay for usage past the free quotas, for example $0.40 per million Cloud Functions invocations after 2 million a month. Prices are from Firebase's pricing page, checked November 10, 2026.

## Services That Are Free on Both Plans

A/B Testing, Analytics, App Distribution, Cloud Messaging (FCM), In-App Messaging, Performance Monitoring and Crashlytics for mobile apps are listed as no-cost.

## Firebase Free Quotas and Blaze Rates

| Service | Free quota (Spark and Blaze) | Blaze rate above quota |
| --- | --- | --- |
| Firestore stored data | 1 GiB | Google Cloud pricing |
| Firestore reads | 50,000 a day | Google Cloud pricing |
| Firestore writes | 20,000 a day | Google Cloud pricing |
| Cloud Functions invocations | 2M a month (Blaze only) | $0.40 per million |
| Cloud Functions outbound data | 5 GB a month (Blaze only) | $0.12 per GB |
| Authentication | 50,000 monthly active users | Google Cloud pricing; phone auth billed per SMS |
| Hosting storage | 10 GB | $0.026 per GB |
| Hosting data transfer | 360 MB a day | $0.15 per GB |
| Cloud Storage (legacy appspot bucket) | 5 GB stored, 1 GB a day downloaded | $0.026 per GB stored, $0.12 per GB downloaded |
| App Hosting bandwidth | n/a on Spark | 10 GiB a month free, then $0.20 per GiB uncached |

Spark does not include Cloud Functions or App Hosting at all. Phone authentication is billed per SMS on Blaze.

## SQL Connect and Cloud SQL

Firebase SQL Connect gives a 3-month no-cost trial of a Cloud SQL for PostgreSQL instance. After the trial, Firebase says instances start as low as $9.37 a month, depending on region and configuration. On Spark, an instance not upgraded to Blaze by the end of the trial is archived, then deleted 90 days later.

## How to Avoid a Surprise Firebase Bill

- Set a budget alert in Google Cloud for your Blaze project.
- Watch Firestore reads: a screen that re-reads a large collection on every load is the usual cause of high bills.
- Cache images and static files so Hosting and Storage downloads stay inside the free quota.
- Use the Google Cloud pricing calculator for apps at scale, as Firebase recommends.

## Is Firebase Worth It?

For a new mobile app, Spark covers development and a small launch for free, and Blaze stays cheap while you are inside the daily quotas. Costs become harder to predict at scale because they track usage closely. Teams that prefer a fixed base fee often compare it with Supabase.

## Firebase Alternatives

| Backend | Free tier | Paid starting point |
| --- | --- | --- |
| Firebase | Spark | Blaze, usage only |
| Supabase | 2 projects, 500 MB database | $25 a month (Pro) |
| Vercel (hosting) | Hobby | $20 a month (Pro) |

See our [Supabase pricing](https://superapp.dev/blog/supabase-pricing) and [Vercel pricing](https://superapp.dev/blog/vercel-pricing) guides. FlutterFlow and many other builders connect to Firebase. As a disclosure, Superapp is our product, so weigh this accordingly. Superapp turns a plain-English description into a native Swift app for iPhone, iPad, Apple Watch or Mac, or a web app with a cloud backend, and prepares the App Store submission, so you do not configure Firebase yourself. It does not build Android apps.
