The short version

  • Each has a real cost: 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; TrueNAS requires self-hosting on x86 hardware, no managed cloud offering; organisations must provision, configure, and maintain their own infrastructure

Where each one falls short

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

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

TrueNAS

  • Requires self-hosting on x86 hardware, no managed cloud offering; organisations must provision, configure, and maintain their own infrastructure
  • ZFS filesystem entails high memory requirements (1 GB RAM per 1 TB of storage recommended), increasing costs for large deployments
  • Limited ARM/embedded support; Community Edition is primarily x86-64, reducing deployment options for edge installations
  • Clustering and replication setup requires operational expertise; misconfiguration can lead to data loss
  • Enterprise support and SLA guarantees require paid subscriptions; Community Edition relies on peer-based forums
