Where each one falls short

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

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result

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
