The short version
- Each has a real cost: Deno the runtime itself is MIT licensed per the project's GitHub repository (denoland/deno LICENSE.md) with no cost, but Deno Deploy's free tier caps at 1 million requests and 15 CPU hours per month, per deno.com/deploy/pricing (Aug 2026); Node.js slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
