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

Packer

  • Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
  • Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence
