The short version

  • Only Deno Deploy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations; PlanetScale eBS High Availability requires 3-node configuration with replication overhead
  • They diverge on capability: Deno Deploy covers Edge Functions, PlanetScale covers Database Branching.
