Supabase Auth Limits: When You Need More

Supabase Auth is a powerful tool that covers 80% of use cases well. It provides a simple, scalable, and secure authentication system that many developers rely on. However, for enterprise-level applications, there are limitations that can hinder growth and innovation.

Where Supabase Auth Falls Short

Supabase Auth is built on top of PostgreSQL and provides a robust set of features for authentication, including password-based login, OAuth2, and JWT-based tokens. However, it lacks the enterprise-grade features that many organizations require, such as:

  • Comprehensive enterprise SSO — Supabase now supports SAML 2.0 via the SSO feature, but LDAP and Kerberos are not supported, and configuration is more limited than dedicated identity platforms
  • Custom licensing and billing models
  • Feature flags and dynamic configuration
  • High availability and disaster recovery

These limitations can be a significant problem for organizations that need more than what Supabase Auth offers.

Key Insight: Supabase Auth is great for small to medium-sized applications, but for enterprise-level use, it's not enough.

When You Need More Than Supabase Auth Offers

For organizations that need more than what Supabase Auth offers, there are alternatives. One such alternative is Bastionary, a self-hosted platform that provides authentication, billing, licensing, and feature flags in a single, unified system.

Bastionary is designed for enterprise-level use and provides the following features:

  • Custom SSO and identity management
  • Flexible licensing and billing models
  • Dynamic feature flags and configuration
  • High availability and disaster recovery

These features make Bastionary a powerful alternative to Supabase Auth for organizations that need more than what it offers.

Conclusion

Supabase Auth is a great tool for many use cases, but for enterprise-level applications, it's not enough. For organizations that need more than what Supabase Auth offers, there are alternatives like Bastionary that can provide the features needed to grow and innovate.
