Frequently asked questions
How much does Firebase cost?
Firebase has no fixed monthly plan: the Spark plan is free with generous limits, and the Blaze plan is pay-as-you-go where you pay only for usage beyond free quotas. Small apps often stay at $0.
Is Firebase free to use?
Yes, the Spark plan is free and covers light usage of Firestore, Authentication, Hosting, and more. Upgrading to Blaze keeps the free quotas and bills only for usage beyond them, but requires a billing account.
How does Firebase pricing compare to Supabase?
Firebase Blaze is pure pay-as-you-go, so costs scale with reads, writes, and bandwidth and can be unpredictable. Supabase Pro is a flat $25/mo per project with predictable limits. Firebase suits spiky workloads; Supabase suits teams that want a fixed bill.
