Where each one falls short

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

shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

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
