Chef Infra vs pyinfra

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.

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.
