Where each one falls short

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

Flagsmith

The Free plan supports only a single team member, limiting collaboration for small teams.
Exceeding request limits triggers overage charges after a one-time 30-day grace period.
Enterprise-grade SSO and governance are locked behind the Scale-Up and Enterprise tiers.
Self-hosting requires operating and updating the platform yourself, unlike a fully managed SaaS competitor.

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.
