Editorial take
Why it stands out
Firebase is not one bill; it is a bundle of product-level meters that happen to live under one console. Treat Auth, Firestore, Functions, and Storage as separate budget lines from the start.

firebase.google.com/pricing (March 2026) contrasts Spark (no-cost) vs Blaze (pay-as-you-go). Illustrative Spark caps include Firestore standard edition about 20,000 document writes/day, 50,000 reads/day, 20,000 deletes/day, 1 GiB stored, 10 GiB/month network egress; Cloud Storage legacy buckets about 5 GB stored, 1 GB/day downloaded; Authentication with Identity Platform about 50,000 MAUs free and 50 SAML/OIDC MAUs free. Blaze adds usage beyond those pools at Google Cloud list rates (e.g. Functions about $0.40 per million invocations after 2M/mo free, outbound networking after 5 GB/mo free at ~$0.12/GB on the table snapshot).
App Hosting (newer row) cites 10 GiB/month no-cost outbound bandwidth from Aug 1, 2025 marketing, then ~$0.20/GiB uncached and ~$0.15/GiB cached. Eligible new accounts may receive $300 in credits via Google Cloud signup flows linked from the pricing page.
Always open the Blaze calculator and set budget alerts—read amplification is the classic bill shock.

Pricing snapshot
Firebase pricing still centers on Spark and Blaze. Spark is the permanent free plan with product-specific quotas across Firestore, Storage, Hosting, and Auth. Blaze is pay as you go on top of Google Cloud billing, and each Firebase product keeps its own free tier before usage charges begin. Google also advertises new-account cloud credits in some signup paths, but those are onboarding promotions rather than a Firebase plan tier.
