Where each one falls short

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

Consul

  • Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
  • Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
  • Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
  • Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
  • Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
  • HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead

OpenHAB

  • Requires a 64-bit Java 21 JVM to be installed and maintained separately
  • Oracle Java is explicitly not recommended by the project because of potential licensing restrictions
  • The recommended hardware is a dedicated Raspberry Pi 4 or newer rather than shared hardware
  • Some version upgrades require additional manual steps run through a separate upgrade tool
