| Pricing | Enterprise SSO from $125/connection/month (third-party sourced; vendor pricing page not retrievable this session) · free tier: AuthKit/User Management free to 1,000,000 MAU, including email/password, social auth, Magic Auth, MFA, bot protection, identity linking, org modeling and domain verification; staging SSO and Directory Sync connections are unbilled | $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. |
| Pricing model | Freemium with per-connection subscription add-ons | Usage-based (two plans: no-cost Spark and pay-as-you-go Blaze) |
| Best for | B2B SaaS companies with an enterprise sales motion and ACVs comfortably above ~$1,500/year per SSO customer that need SAML, SCIM and audit logs shipped in weeks, especially where MAU volume is high but the paid connection count is modest. | 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. |
| Avoid if | You want to offer SSO on a low-priced self-serve tier, you are building a consumer/B2C app needing adaptive risk and fraud detection, you need granular RBAC or Auth0-style session management out of the box, or you require a deep current review corpus before taking on a core dependency. | 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. |

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.
