Puppet vs pyinfra

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.

pyinfra is a free, Python-native tool for automating infrastructure across servers. It connects over SSH to run commands concurrently and idempotently, using Python deploys and inventories. Operations can describe a desired host state or issue specific commands, and `--dry` previews per-host changes before applying them. The project says it works from one host to 10,000, with parallel execution and real-time output. Target machines need a shell and SSH, but no agent, daemon, state file, or control plane. Documented connectors include SSH, Docker, Terraform, and the local machine; operations cover package managers, files, services, databases, security, and containers. It runs wherever Python runs, with Mac, Linux, and Windows listed as control systems. Python 3.10 or later is required; pyinfra 3.5.1 and later supports Python 3.10 through 3.13. The software is MIT licensed. The installation guidance recommends keeping pyinfra and its dependencies current and installing as a regular user rather than as root or with sudo.
