The short version

  • Each has a real cost: Lambda (AWS Serverless) billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does; Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, Deno Deploy covers Edge Functions.
  • Prices and features above were last checked on 30 August 2026.
