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; Zabbix the database is the scaling limit, and high frequency polling grows history tables fast enough that untuned installations hit housekeeping stalls and query timeouts within months.
  • They diverge on capability: Packer covers Image building, Zabbix covers Agent and agentless collection.
  • 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.

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

Zabbix

  • The database is the scaling limit, and high frequency polling grows history tables fast enough that untuned installations hit housekeeping stalls and query timeouts within months.
  • Initial configuration is heavy; getting useful alerting rather than noise requires understanding trigger expressions, macros and template inheritance, which is a multi-week learning curve for a team new to it.
  • The AGPLv3 change at version 7.0 affects anyone offering Zabbix over a network as part of a commercial service, and that obligation is easy to inherit accidentally during an upgrade.
  • The web interface is functional rather than pleasant, and many sites end up running Grafana alongside it purely for presentation, which is a second system to maintain.
  • Upgrades between major versions touch the database schema and can take hours on large history tables, so the maintenance window is proportional to how much data you kept.

Answered from the vendors’ own pages

Packer: How much does HashiCorp Packer cost?

Packer does not publish specific pricing on its website. The open-source Packer tool is free, while HCP Packer (HashiCorp's cloud-hosted version) offers a free trial, but detailed pricing requires contacting HashiCorp.

Source
Zabbix: Is Zabbix genuinely free for commercial use?

The software has no licence fee at any scale. From version 7.0 it is AGPLv3, so offering it as a network service to third parties carries source distribution obligations.

Zabbix: What is the real cost of running it?

Database administration and the person who tunes it. Budget for PostgreSQL with TimescaleDB and someone who owns the retention policy.

Zabbix: How does it compare to a commercial per-device tool?

It removes the licence line entirely and adds an operations line. Below a few hundred devices the commercial tool is often cheaper in total; above that Zabbix wins clearly.
