What the Ledger says
Giant Swarm is building toward a Cluster API platform that it operates inside the customer's own provider account, with a Backstage portal and, since 2026, an agent platform on top. The record shows steady delivery and an open roadmap, but Kubernetes minors reach vSphere a median 290 days after upstream and the on-premises product has no documented bare-metal, air-gap, backup, VM or GPU support. A buyer gets an operated, open-source stack on VMware or Proxmox with low technical lock-in, at the price of a bespoke contract, a slow upgrade cadence and a small partner ecosystem.
AI say-do: 4 announced, 3 GA, 0 preview, 1 pending, 0 dropped. The AI is GPU support, an MCP gateway with user-level identity, an agent runtime and a read-only portal chat; no AI training platform.
