What the Ledger says
Deckhouse is a modular in-cluster platform that bundles its own virtualization, GPU, observability and fleet products and ships a new minor every two to three months. The record is strong on delivery and weak on openness: no public roadmap, a CNCF certification that stopped at Kubernetes 1.31 after Flant left CNCF in 2025, and a 2026 rename and edition reshuffle. A buyer outside Russia gets a capable platform with unproven conformance and unclear purchase terms.
AI say-do: 0 promises found; 2 Enterprise modules (ai-models, ai-inference) both Experimental; no operator assistant and no MCP server found.
