pyinfra

What pyinfra is

pyinfra is a free, Python-native, agentless tool for automating infrastructure across servers. It connects over SSH to run commands concurrently and idempotently, using Python deploys and inventories. Operations can define a desired host state or run specific commands, and the `--dry` option previews changes per host before applying them. The project describes use from one host to 10,000, with parallel execution and real-time streaming output. Target hosts need a shell and SSH, but no agent, daemon, state files, or control plane. Documented connectors include SSH, Docker, Terraform, and the local machine. Operations cover package managers, files, services, databases, security, and containers. pyinfra runs wherever Python runs, with Mac, Linux, and Windows named as supported control systems. Python 3.10 or later is required; pyinfra 3.5.1 and later supports Python 3.10 through 3.13. The tool is MIT licensed. For assistance, the project points users to Matrix and Stack Overflow, and bug reports to GitHub issues. Windows installation requires Administrator privileges, while the installation guide recommends keeping pyinfra and dependencies current and installing as a regular user rather than root or sudo.
