  • Standard rate limits are not published

Chef

  • Priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size
  • Tripling the price between the two published tiers puts compliance and audit features well above basic automation
  • Enterprise Plus and every self managed deployment are custom quoted with no published price
