Where each one falls short

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

Ably

  • Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
  • The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.
  • 24/7 mission-critical support and 99.999% uptime SLAs are reserved for the custom-priced Enterprise tier.

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.
