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

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.
