Best Auth0 Alternatives
Looking for Auth0 alternatives? Compare the top identity providers with better pricing, self-hosting options, and enterprise features.
Why Teams Leave Auth0
Per-User Pricing Gets Expensive
Auth0's per-user model means costs grow unpredictably as you scale. At 10,000 users, you could be paying $25,000+/month.
Enterprise Features Behind Paywalls
SSO, MFA, and compliance features often require expensive enterprise tiers. Why pay extra for security basics?
No Self-Hosting Option
Auth0 is cloud-only. For regulated industries or data sovereignty requirements, this is a dealbreaker.
Support Can Be Slow
Unless you're on an enterprise plan, getting help can mean waiting days. Your auth shouldn't be a bottleneck.
