The short version

  • Only NestJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; NestJS licensed under the MIT License per nestjs.com; the core framework has no paid tier, but the Enterprise support offering (architectural reviews, LTS, upgrade assistance) is sold by direct contact with no published rate

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

NestJS

  • Licensed under the MIT License per nestjs.com; the core framework has no paid tier, but the Enterprise support offering (architectural reviews, LTS, upgrade assistance) is sold by direct contact with no published rate
  • Built specifically on TypeScript and Node.js, per nestjs.com's own description, so it requires that runtime and cannot be adopted independently of the Node.js ecosystem
