Where each one falls short

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

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

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
