Where each one falls short

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

DigitalOcean

  • Free tier includes only 3 static sites; additional static sites require paid upgrade
  • Container registry free tier capped at 500 MiB storage; exceeding requires paid tier
  • Functions free tier allows 90,000 GiB-seconds monthly; overages billed on usage basis
  • GPU Droplets require minimum monthly commitment for lower hourly rates; on-demand significantly more expensive

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.
