5. Credibility: 14.5 / 25

Criterion	Score	Basis
Cadence	3.5	Every release dated in the changelog, 12 minors at 7 to 73 days; no published calendar
Roadmap transparency	2.5	Dated changelog only; no roadmap, no support policy, status page keeps no history
Say-do	2.5	Too few dated promises to judge: one pending MCP preview, one stale FAQ answer on bare metal
Velocity	3.5	Bare metal, OIDC, VPC-only pools, snapshots, GPU pools and applications shipped 2024 to 2026
Lifecycle stability	2.5	Manual upgrades that replace nodes and change IPs; no support window or end-of-life dates published

Say-do record, 2023 to 2026: 2 items in 2023 to 2026: 1 pending (MCP server preview since 2026-05-14), 1 stale statement (marketing FAQ denies bare metal that the changelog added 2024-05-14). No public roadmap; VKE beta to GA in 2021 to 2022 took 9 months.

6. Commercial risk: 6.5 / 25 (lower is better)

Criterion	Score	Basis
Price and licence volatility	1	Control plane free since GA; pricing page text unchanged 2023 to 2026; HA fee not stated
Purchase constraints	0.5	Self-service pay as you go, hourly billing
Channel and access	1	Self-service sign-up, public docs and pricing, 33 locations
Owner stability	1.5	Private company; financials not examined
Cost of staying supported	2.5	No published support window; upgrades manual and replace nodes

Security record of the product itself: none found: no VKE security bulletins published; no cross-tenant or control-plane flaw disclosed 2023 to 2026. The runc fix for CVE-2024-21626 first appears in the 2024-05-14 changelog, 3.5 months after disclosure.

7. Technical lock-in: 9.0 / 25 (lower is better)

Criterion	Score	Basis
Formats	0.5	Certified Kubernetes (CNCF folders 1.24 to 1.37); Calico only
Export path	2	Cluster API and Terraform; no migration or Kubernetes backup service found; bandwidth overage fee not read
Stack coupling	2	Vultr load balancers, block storage classes and VPC reconciled by the service; VPC 2.0 not supported
Hardware / cloud coupling	3.5	Vultr cloud only; no hybrid or on-premises extension found
Skills and tooling coupling	1	kubectl, Terraform and vultr-cli

8. Integrator fit: 10.5 / 20

Criterion	Score	Basis
Partner programme openness	2.5	Partner programme and solution partners listed; tiers not read
Multi-tenancy and self-service	2.5	Vultr IAM policies with Kubernetes actions; no organisation or fleet isolation read
API and infrastructure-as-code	4	Terraform provider 6.1 million downloads (partner tier), Cluster API and Crossplane providers, CLI and Go client
Skills and certification	1.5	No Kubernetes certification found

9. AI leverage: 6 / 20

Strand	Today	Latest step
AI workload support	2	2024: GPU Operator and bare-metal GPU pools from 2024-05-14; no sharing or inference add-ons
AI platform stack	1	2026: Applications tab deploys AMD AI Workbench and OpenFold3 (2026-06 and 2026-07); partner applications, maturity not stated
AI-assisted operations	0	none
Agent openness	3	2026: Official hosted MCP server in preview with OAuth, 11 Kubernetes tools, read-only, from 2026-05-14

AI say-do: 1 announced, 0 GA, 1 preview (MCP), 0 dropped. VKE has GPU pools and an applications catalogue but no AI assistant or inference add-on; first-pass GPU launch dates have no source.

10. Reading

Vultr is building a simple, free-control-plane Kubernetes service that leans toward GPU and bare-metal capacity, with an MCP server in preview. The record shows fast version releases (median 41 days) and steady dated changelog entries, but no roadmap, no support policy, no control-plane SLA and no incident history. A buyer gets cheap standard Kubernetes with strong GPU choices and thin security, operations and sovereignty depth.

11. Open questions and evidence caveats

No support window or end-of-life dates published; end of support is not scored from evidence.
HA control plane price, VKE availability per location and cluster size limits not found.
The SLA is a 100% network and host-node guarantee that excludes the API and control panel; the VKE control plane has no stated SLA.
Status page keeps no history, so reliability could not be assessed; web search quota was exhausted, so launch blog posts for HA, bare metal and GPU pools were not opened.
Marketing FAQ says VKE does not support bare metal; docs and changelog show bare-metal pools.
Etcd encryption is a provider claim; the security guide says Secrets are only base64 encoded unless encryption is enabled.
Compliance: a SOC 2 report is available in the console; scope for VKE not confirmed.
