The short version

  • Each has a real cost: Go no built-in generic types until recent versions, requiring workarounds for type-safe collections; 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
  • They diverge on capability: Go covers Goroutines, Packer covers Image building.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Go

  • No built-in generic types until recent versions, requiring workarounds for type-safe collections
  • Error handling through explicit return values considered verbose compared to exception-based approaches
  • Smaller standard library compared to Python or Java; requires external packages for common tasks
  • Package management can create version conflicts and dependency hell issues

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
