CST VerdictShort answer
Startups and SMBs building multi-tenant SaaS products should choose Frontegg CIAM to ship customer identity without hiring a dedicated IAM engineer; the platform's pre-built multi-tenant architecture and admin portal let product teams delegate identity management to end customers rather than building it themselves. The vendor's 73-person team and cloud-only deployment mean you're not managing infrastructure, and NIST CSF 2.0 coverage in identity management and access control confirms baseline security controls are present. Skip this if you need deep compliance certifications like FedRAMP or SOC 2 Type II attestation before deployment, or if your customer base demands on-premises options. Startups and mid-market teams building custom applications need Keycloak because it's open-source IAM you can actually modify without vendor lock-in, and self-host it on infrastructure you already control. The tool supports OAuth 2.0, OpenID Connect, and SAML protocols out of the box, plus passkey-based MFA and multi-tenancy through its Organizations feature, covering NIST CSF 2.0's Identity Management function without licensing per user. Skip this if your organization needs managed SaaS convenience and hands-off operations; Keycloak requires DevOps capacity to deploy, patch, and maintain in production.
