Firebase Authentication vs Appwrite
Both platforms are scored with the same methodology and the same category rubric. Nothing on this page is influenced by advertising.

| Pricing | $0.0055 per MAU/month above 50,000 Tier 1 MAUs (Blaze plan, pay-as-you-go) · free tier: Spark plan: no payment method required; other authentication services (email, social, anonymous) included at no cost; Phone Auth listed as 'Not applicable'. With Identity Platform: 50,000 MAUs free and 50 SAML/OIDC MAUs free. | From $25/month (Pro) · free tier: Free $0: 5GB bandwidth/mo, 2GB storage, 750K executions, 75K MAU, 2 projects, community support; projects paused after 1 week of inactivity |
| Pricing model | Usage-based (two plans: no-cost Spark and pay-as-you-go Blaze) | Subscription with published usage overages |
| Best for | Consumer-facing mobile or web products with standard email/social/phone sign-in needs, especially teams already committed to Firestore or the wider Firebase/Google Cloud stack, and startups whose user base fits inside the 50,000 free MAU allowance. | Solo developers, indie teams and startups building a full app — auth, data, storage, functions and website — who want one vendor, hard budget caps and the option to self-host later; mobile-first Flutter and React Native teams are a particularly strong fit. |
| Avoid if | You sell enterprise SSO (SAML/OIDC billed at $0.015/MAU after 50 free users), need deep customization of login flows or fine-grained authorization, run high-volume SMS auth in expensive regions, require contractual data residency, a published SLA or a named compliance attestation, or have a hard multi-cloud portability mandate. | You need a contractual uptime SLA, SSO, WAF or SOC-2/HIPAA below a custom Enterprise contract, must pay by invoice or PO, plan to run production on the Free tier, host many client projects on one plan, or require substantial independent review evidence before buying. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
