The short version
- Only Node.js has a free tier, so it costs nothing to try first.
- Each has a real cost: Node.js slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms; Express.js governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Express.js
- Governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare
- Express.js provides only a thin layer of fundamental routing features by its own description, requiring separate middleware modules for functionality like body parsing, sessions or authentication
