Credibility: 14.0 / 25

Criterion	Score	Basis
Cadence	3.5	19.x builds every one to two months and Chef 360 roughly monthly; a tentative dated roadmap for 2026
Roadmap transparency	3	Tentative 2026 roadmap published 2026-02-27 and a public lifecycle table; the table contradicts the docs on Supermarket and lists dates before its own publication
Say-do	2.5	Linux ARM and FIPS shipped about a month late; Infra Server retired within a year of 15.x; the AI Assistant is still a beta
Velocity	3.5	Habitat re-platform, Target mode, Chef 360 HA and single sign-on within two years
Lifecycle stability	1.5	Hosted Chef ended 2024-11-30, open source Infra Server ends 2026-11-30, Automate deprecated 2026-11-01, Supermarket deprecated, Omnibus replaced by Habitat, 17 and under ended 2026-02-05

Commercial risk: 17.0 / 25 (lower is better)

Criterion	Score	Basis
Price and licence volatility	4	Proprietary binaries since April 2019; licence-key regime for all official downloads from 2025-12 to 2026-09; per-node prices not published
Purchase constraints	3	Production needs a commercial per-node licence; the free key is non-production only
Channel and access	4	Licence key for every official binary; unauthenticated downloads removed in phases; gem installs need a key at runtime
Owner stability	2.5	Listed owner since October 2020; products consolidated into Chef 360, with Hosted Chef and the open source server ended
Cost of staying supported	3.5	Infra Server users must move to Chef 360 or Cinc by November 2026; Automate users by November 2027

Technical lock-in: 11.0 / 25 (lower is better)

Criterion	Score	Basis
Formats	3	Ruby cookbooks, Policyfiles and node objects on the server
Export path	3	Documented migration to Cinc Server; moving to another tool means rewriting cookbooks
Stack coupling	1.5	Any OS; Habitat packaging and Chef 360 on Kubernetes bring their own tooling
Hardware / cloud coupling	0.5	None
Skills and tooling coupling	3	Chef and Ruby skills, a shrinking pool

Integrator fit: 11.0 / 20

Criterion	Score	Basis
Partner programme openness	2.5	Partner programme terms not found; vendor sells direct and through AWS Marketplace
Multi-tenancy and self-service	2.5	Chef 360 RBAC, custom roles and environments; no tenant model for service providers
API and infrastructure-as-code	3.5	Server REST API, Automate and Chef 360 APIs
Skills and certification	2.5	Training exists; certification not found

AI leverage: 2.5 / 20

How the product uses AI, scored per year like capability. Only GA counts.

Criterion	2019	2022	Today	Latest step
AI code and plan generation	0	0	0	2015: None
AI platform stack	0	0	0	2015: None
AI-assisted operations	0	0	0.5	2026: Chef 360 1.7.1: Chef AI Assistant beta, invite-only, SaaS only
Agent openness	2	2	2	2015: Chef Server and Automate REST APIs with keys; no official MCP server

Year by year: 2015: 2 · 2016: 2 · 2017: 2 · 2018: 2 · 2019: 2 · 2020: 2 · 2021: 2 · 2022: 2 · 2023: 2 · 2024: 2 · 2025: 2 · 2026: 2.5

AI say-do, 2023 to 2026: 1 AI items announced; 0 GA, 1 still preview, 0 pending, 0 dropped. The one AI item is an invite-only beta in the SaaS edition.

Chef has no generally available AI feature. The assistant announced in May 2026 is an invite-only beta on the SaaS edition, and there is no official MCP server, so the only agent path is the REST API.

Reading

Chef still converges Linux and Windows fleets as well as any tool here, and Infra Client 19 added agentless Target mode and a Habitat build. The buyer-facing story since late 2025 is the retirement of everything that was free to run: the open source Infra Server stops in November 2026, Supermarket and Automate are deprecated, and every official download needs a licence key. Chef 360 is the replacement, sold per node without published prices. A buyer should decide before November 2026 whether the server moves to Chef 360 or to the Cinc Server fork, because the cookbooks run on either.

Open questions and items to re-score

Chef 360 prices, and whether it requires Infra Client 19 or supports 18.
GA date of the Chef AI Assistant (beta since 2026-05-12).
Date of the Chef Marketplace that replaces Supermarket.
Maintainer and last release of knife-vcenter and kitchen-vcenter.
Whether Infra Client 19 FIPS mode is fully supported; the changelog shows testing in 19.2.12.
No sourced 2023 item was found, so the direction table starts in 2024.
