The short version

  • Each has a real cost: Blacksmith per-minute pricing model requires estimating usage to predict costs; Node.js slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
  • They diverge on capability: Blacksmith covers Bare metal runners, Node.js covers V8 JavaScript engine.
  • Prices and features above were last checked on 30 August 2026.
