What the Ledger says
MAAS does one job, bare-metal commissioning and deployment, and does it with a clear support price list, which is rare in this group. Its capability total is low because the Ledger scores the whole automation stack and MAAS has no configuration engine, no plan mode and no cloud or hypervisor API beyond LXD and libvirt; the Terraform provider from Canonical is the only declarative path. Credibility is middling: the stated six-month rhythm has slipped to eight or nine, and 3.8 has been a release candidate since August 2026. The one thing to check is which features your estate needs from the paid tiers, because HA and RBAC are listed there.
MAAS has no AI features and no official agent interface beyond its REST API. Its AI relevance is on the hardware side: 3.7 commissions and deploys NVIDIA BlueField-3 DPUs.
