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

StackBlitz

  • Specific Teams and Enterprise pricing figures are not published; visitors must request a quote or infer from the pricing calculator.
  • Browser-based execution via WebContainers has limits on which native/binary dependencies can run compared to a real server-backed environment.
  • Heavy or resource-intensive workloads may be constrained by the end user's own browser and machine resources.
