Where each one falls short

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

Bootstrap

  • Default styling is recognisable, so sites can look generic without deliberate customisation
  • Ships a large stylesheet, and unused CSS must be purged to keep payloads reasonable
  • Component-based approach fits less naturally into React and Vue codebases than libraries designed for them

Crossplane

  • Requires Kubernetes expertise and infrastructure
  • Steep learning curve for teams new to Kubernetes patterns
  • Provider ecosystem smaller than Terraform
