Where each one falls short

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

Tailwind CSS

  • HTML markup becomes verbose with many utility classes (class="flex items-center justify-between bg-gradient-to-r..."); readability challenges for complex layouts
  • Limited animation library compared to dedicated animation tools (Framer Motion); complex transitions require custom CSS or JavaScript
  • Customisation beyond configuration requires editing generated CSS or writing custom utilities; not as flexible as hand-written CSS for unique designs
  • Tailwind Plus (components, templates) is paid; developers seeking production-ready component libraries must purchase or build custom

Vault

  • Vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
  • The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
  • Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
  • Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
  • A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
