The short version

  • Only Lambda (AWS Serverless) has a free tier, so it costs nothing to try first.
  • 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; Koyeb pricing starts at $29/month with additional compute costs
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, Koyeb covers Serverless containers.
  • Prices and features above were last checked on 30 August 2026.
