Spec score 7.5 #18 of 26 in Configuration Management Tools

What it is

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.
