Ansible

  • The open source project gives the engine and the language; the automation controller, automation mesh, automation hub, analytics and governance all belong to the paid Red Hat Ansible Automation Platform
  • Event-Driven Ansible and the AI coding assistant are platform features rather than open source ones
  • Red Hat does not publish platform pricing
  • Running open source Ansible at scale means building the control plane the platform otherwise provides

Checkmk

  • Pricing calculated by service count, not hosts (approximately 30 services per host on average)
  • Professional support limited to 8-10 hours per week on base plans
  • Synthetic monitoring is separate add-on with per-test pricing
