OpenDSC vs Puppet

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.

Puppet Enterprise provides policy-driven configuration management and infrastructure automation for complex cloud and hybrid environments. It uses policy as code to continuously enforce desired state, helping organizations identify and remediate configuration drift. Both agent-based and agentless management are supported, with a web interface and role-based access control. Puppet Enterprise Advanced adds continuous enforcement of CIS Benchmarks and DISA STIGs, self-service automation, AI features, observability integrations, and advanced patching. It also integrates with third-party vulnerability scanners, including Nessus, for remediation. Listed integrations include GitHub, AWS, Microsoft Azure, Google Cloud Platform, HashiCorp Vault, and ServiceNow. Agents are listed for Linux, Windows, and macOS. Puppet describes the product as suited to medium and large organizations managing complex environments that require security, compliance, and centralized automation. Pricing is custom; a free trial runs on up to 10 nodes with no commitment or time limit. Network and edge device management is optional, and licensing for those devices requires contacting sales.
