The short version

  • Only Deno has a free tier, so it costs nothing to try first.
  • 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); 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

  • 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)
  • Deno Deploy Pro at $20 per month charges $2 per additional million requests and $0.05 per additional CPU hour once the included quota is exceeded, per deno.com/deploy/pricing

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
