Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Auth0

Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
Advanced features like MFA and RBAC only available on paid Essentials tier and above
Ownership by Okta introduces risk that independent product roadmap may change

Frontegg

Detailed per-unit pricing beyond the free tier is not published, requiring use of an online calculator or sales contact to estimate costs.
Advanced fraud protection and multiple environments are Enterprise-only, unavailable on the Pay As You Go plan.
The 7,500 free monthly active users is comparatively modest next to some competitors' free tiers.
As a broader CIAM platform, it can be more complex to integrate than lighter-weight developer-first auth tools for smaller apps.
