Where each one falls short

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

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.

Wasabi

  • 90-day minimum storage duration with no option to delete before full period without penalty
  • Significantly smaller global footprint than AWS with only 16 regions, resulting in higher latency for users in underserved regions
  • Performance can degrade with high-volume transactions requiring throughput management strategies
  • Hot storage only, no cold/archival storage tier for long-term data at lower cost
  • Support responsiveness gaps with teams experiencing multi-day waits for critical issue resolution
