The Picari read
FusionAuth provides API-driven IAM for customer-facing applications, with SSO, MFA, passwordless login, and role-based authorization built around OpenID Connect, OAuth 2.0, and SAML. Its key differentiator is deployment control: buyers can run it self-hosted, on-premises, hybrid, or air-gapped. It fits teams that need embedded identity infrastructure for B2C, B2B, or partner access.
- Engineering-led organizations and B2B SaaS companies that require full architectural control, self-hosting capabilities, and predictable pricing for customer identity and access management (CIAM).
- Multi-tenant B2B SaaS authentication
- Self-hosted/on-premise identity infrastructure
- Custom customer-facing registration and SSO flows
- Migrating off legacy identity providers (e.g., Auth0)
