What the Ledger says
Ironic has the highest credibility in this group: a six-month cycle with published dates, public specs and deprecations that land when promised. Its capability total is low because the Ledger measures the whole automation stack and Ironic is a bare-metal engine only, with no plan mode, no configuration engine and no VM or cloud targets; within the bare-metal domain it is the deepest tool scored. Sustainability risk is the lowest of the three community projects because a foundation owns it and three vendors sell it. Check the hardware list before upgrading: 2026.2 retired the SNMP, iRMC and iLO hardware types, leaving Redfish as the main path for older servers.
Ironic has no AI features and no official agent interface beyond its REST API. OpenStack clouds run AI workloads on Ironic nodes, but nothing in Ironic itself targets AI.
