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; Helicone the free Hobby plan is capped at 10,000 requests per month, which teams with production traffic can exceed quickly.
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, Helicone covers Request dashboard and tracking.
