Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deno Deploy

Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
Less mature than established serverless platforms; newer company and platform
1GB deployment size limit may restrict larger applications
512MB memory limit lower than some competitors for memory-intensive workloads
Smaller user base and community compared to Lambda or Netlify

PromptLayer

The free plan is capped at only 2,500 requests per month, quite limited for active production use.
The Team plan jumps to $500/month, a large step up from the $49/month Pro plan.
Overage transaction fees apply on top of subscription costs, which can make total spend less predictable.
Enterprise-grade features like HIPAA BAAs and custom deployment require contacting sales.
