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.

  • As a broader CIAM platform, it can be more complex to integrate than lighter-weight developer-first auth tools for smaller apps.
