The short version
- Only Node.js 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; Node.js slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms

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
Node.js
- Slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
- Requires separate setup for TypeScript support unlike Deno which treats TypeScript as native
- Larger memory footprint on startup compared to lightweight alternatives like Deno
