Side-by-side decision briefs that show when each product tends to fit, what usually breaks first, and how pricing behavior differs.
Okta vs Auth0 is a category mismatch unless you’re clear on who you’re authenticating. Use Okta when employees need governed access across many SaaS apps with audit controls. Use Auth0 when customers need flexible login and enterprise SSO readiness inside your product, and you want to avoid building identity infrastructure.
Auth0 vs Cognito is a decision between buying a platform and owning primitives. Choose Auth0 when enterprise SSO readiness, logs, and CIAM patterns reduce delivery risk. Choose Cognito when you want AWS-native building blocks, accept more engineering ownership, and need a cloud-first identity layer you can tailor.
Clerk vs Firebase Auth is about speed and product UX vs stack alignment. Choose Clerk if you want a polished, managed auth experience and B2B org primitives without building. Choose Firebase Auth if your product is mobile-first, you’re already on Firebase, and your identity requirements are standard—with a plan to upgrade when enterprise SSO arrives.
Entra ID vs Okta is an ecosystem decision. Choose Entra if your workforce lives in Microsoft 365/Azure and you want identity controls aligned with Microsoft tenant management. Choose Okta if you have a heterogeneous SaaS stack and want an IdP that prioritizes vendor-neutral integrations and identity governance patterns across many apps.
Okta vs OneLogin is a workforce IAM choice. Choose Okta when you need deep governance patterns, broad integrations, and mature admin/audit controls across a heterogeneous SaaS estate. Choose OneLogin when your needs are centered on workforce SSO and MFA and you want a simpler fit, accepting that governance depth and ecosystem maturity may differ by requirement.
Entra ID vs OneLogin is a workforce IAM decision anchored in ecosystem alignment. Choose Entra if your workforce identity and security stack are Microsoft-first and you want identity controls aligned with Microsoft tenant management. Choose OneLogin if you want a non-Microsoft workforce IdP option for SSO/MFA in mixed SaaS environments and you can validate governance requirements against your rollout plan.
Auth0 vs Clerk is a decision between enterprise CIAM readiness and speed-to-production. Choose Auth0 when you need CIAM flexibility, enterprise SSO building blocks, and a long-term identity platform for B2B requirements. Choose Clerk when you want to ship a polished auth experience quickly with minimal engineering overhead, and your enterprise requirements are either limited or planned for explicitly.
Firebase Auth vs Supabase Auth is primarily a stack decision. Choose Firebase Auth if you’re mobile-first, already using Firebase services, and want lightweight SDK auth with minimal backend work. Choose Supabase Auth if your product is Postgres-first and you want auth + database authorization (RLS) to be the same system—accepting that enterprise identity requirements may later require a dedicated CIAM layer.
