The short version

  • Only Deno has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog consumption-based pricing model makes costs hard to predict and can scale quickly; 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)
