Where each one falls short

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

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward

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.
