Chef Infra vs OpenDSC

Chef Infra automates infrastructure configuration and helps keep systems aligned with a defined desired state. Teams express configurations and policies as code, test them, and deliver them through automated pipelines; Chef Infra can correct configuration drift when systems diverge. It supports Windows and Linux systems, cloud ARM systems, and Mac laptops across on-premises, cloud, and edge environments. Chef Infra Client includes more than 150 resources, while the community provides thousands of configuration templates. Chef Workstation bundles the client with Chef InSpec, Chef Habitat, Test Kitchen, Cookstyle, and Chef Upgrade Lab. The policy language is Ruby DSL, and listed capabilities include policy testing, reporting, and CI/CD integration. The free community version is non-commercial. Business costs $59 a year per node, and Enterprise costs $189 a year per node; Enterprise Plus requires a customized quote. Chef Infra Client 19.x is listed as the current LTS release, while 18.x is deprecated and earlier versions are end of life.

OpenDSC is a configuration management platform for Microsoft Desired State Configuration, intended for teams managing settings across infrastructure nodes. Its Local Configuration Manager monitors system state and can automatically correct configuration drift. For centralized management, the pull server registers nodes, distributes configurations, and provides compliance reporting through a web dashboard and REST API. Configurations can be versioned, assembled into composite deployments, and parameterized by region, environment, or node. Local file-based configurations support disconnected use as well as server-driven pulls. The resource library covers Windows administration, SQL Server, and file, JSON, XML, and archive tasks across Windows, Linux, and macOS. The Resource Development Kit provides .NET libraries and tools for developing custom resources. The pull server supports OpenID Connect providers, client-certificate mutual TLS, role-based access control, and retention policies. SQLite is supported for development, while production deployments can use SQL Server or PostgreSQL. The project is MIT licensed and self-hosted. Its roadmap lists native Linux and macOS LCM services, distribution packages, and official Docker deployment as planned work.
