| Pricing | Starter from $162/mo (billed annually, at the page default of 1,000 MAUs), community-forum support only, basic hosting included · free tier: Community — free, unlimited, self-hosted with core authentication features and community support (forums, Slack, GitHub); passkeys/WebAuthn and biometrics reportedly require registering a free Community licence | 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 |
| Pricing model | Subscription (MAU-based tiers; free self-hosted Community edition) | Freemium with per-connection subscription add-ons |
| Best for | Engineering-led B2C or mid-market B2B SaaS teams that need data sovereignty or on-prem CIAM, are comfortable with OAuth2/OIDC concepts, and want an API-first platform they can start free and later move to managed hosting without switching vendors. | 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. |
| Avoid if | You lack dedicated engineering capacity for identity work, require a truly open-source core, need 24x7 support or an SLA on a small budget, need cheap SCIM provisioning, or require FedRAMP or Zanzibar-style fine-grained authorization. | 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. |

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.
