  • Free services are capped at specified monthly amounts, and only some of them are always free

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

  • Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence
