Where each one falls short

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

OneTrust

  • Complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable
  • No published pricing examples or per-unit costs; all pricing requires custom quotes
  • Each solution area uses different pricing metrics, requiring complex calculations for multi-solution purchases
  • Enterprise-only positioning (Fortune 500 focus) suggests premium pricing, discouraging mid-market or startup adoption
  • Platform complexity and multiple solution areas may result in significant implementation and ongoing costs not disclosed upfront

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan
